Although we were originally a bit reluctant at spending nearly £300 on trying to improve our 1.9 VW Touran (66 kW model), the tuning box has changed the car from a gutless, unresponsive lump of metal, which we were thinking of getting rid of, into something which has immediate throttle response, even up the fairly steep hills round here, and which can now overtake any vehicles and not just those going at tractor-pace.
 
It's also made a dramatic difference to towing our race-car trailer.
 
It's perhaps too early to say but our fuel consumption is certainly no worse and is probably going to be quite a bit better than before the box was fitted.
 
In all, it's been one of the best investments we've made recently and has made driving something near enjoyable again.

The car runs like a dream! Sooo much more torque and the car seems alot more responsive as well. The car just takes off!
Before the Passat I owned an Octavia vRS TDI and my newly modified load lugger would easily be a match for it now.
Thanks so much for all your time and effort. When I change the car again I'll certainly be in touch!!

I was unsure if the Tuning system was worth buying or not but since I was planning a 3 week trip though the Alps towing a trailer I spoke to TDI Tuning. After speaking to their team I went ahead and ordered one. The box arrived very quickly and I installed it the day before I left, in about 30mins.
What a difference it made to my Discovery! It is now a lot more drivable with no flat spots and pulls away at junctions etc much better than before. But more importantly I made it over 8 mountain passes in the Alps without having to resort to 1st gear or full throttle. It easily pulled the trailer up even the steepest of tracks - something that I am sure it wouldn't have done before the box was fitted.
Better still, the fuel economy savings are amazing. Discovery was much more drivable and felt like a new car. I would recommended fitting one if you have a TD5 especially if you tow.

As an Industrial engineer I have designed engine parts for automotive companies and so know quite a bit about engine design .So I was initially sceptical to try out the TDI tuning box for my 2008 Ford Focus 2.0 TDCI as it still has the maintenance plan on it . But researching it further with other automotive industry colleagues I found out that major automakers like VW, Audi, Ford, Alfa, BMW, Mercedes who develop diesel engines all leave a lot of room for improvement for the next application of the engine. Take Audi as an example.....it has the standard 103 KW 2.0 TDI and also a 125KW 2.0 TDI. That's a 22 KW and X amount of torque difference!!! How do they do that? Well they do exactly what the TDI tuning box does, they simply alter the ECU mapping amongst some other smaller changes. The TDI box grabs the original ECU signal and refines it to ensure optimal performance.

Since fitting (very simple) the TDI tuning box, i have had much better mid range pick up from 1300 rpm and as smooth as silk performance, even at idling. I would easily say improvements are as advertised. 100kw to 120kw and 320 NM to 380NM. Which puts my humble Focus at same output levels as the top brands. When it comes to the service I'll take the box off, and put box in the cupboard. So reliability does not even enter as an issue with the way TDI have worked it.

I am impressed.

I have enclosed a photo of my BMW 330D, This is message for anyone that is considering a TDI-Tuning Box.

I had ordered a system for my vehicle from a different tuning company, in which I had some issues and they were never there to take my calls. Finally they refunded me my money (after weeks of no reply)

I was very reluctant about the tuning box's but I contacted TDI-Tuning, straight away the customer service was outstanding. They assured me they would help me through the process. I happen to live relatively local so I drove over. I couldn't believe how easy it was to fit, as I was on my way in 10 minutes.

I am now saving about £20 a week on fuel. Thanks again TDI for giving me faith again in tuning.

Just fitted the tuning box to my car, it really does what it says on the tin! Couldn't believe it was so easy to fit. My 2011 Navarra is not sluggish anymore, I have so much power, it's amazing. The extra efficiency is also a little Gem!

Super fast delivery I ordered Wednesday morning and it had arrived Thursday morning. I am really please with this product!

Mike O'leary

I have to say was a little optimistic about Tuning Boxes at first with what I had been reading on internet forums. However, 6 months later I've now bought a second one from you. The wife was so impressed with the fuel savings I received from my Tuning Box for my Audi A4 that I purchased last month, she wanted one too! So bought one of your CRTD2 box's for my wife's 2010 Golf 2.0 TDI. The Golf now does an extra 7 MPG and she's over the moon!

Thank you guys! Top quality product! You are well recommended to friends and family, we couldn't fault the service!

Christopher Sullivan

Hi,
Thanks for the extremely fast delivery of my tuning box. I must admit I was a little sceptical about the claims made on the advertising blurb but now its fitted I can't believe how accurate it all is. It took under 10 mins to fit to my car as the engine cover just pulls off and the connection point is obvious from the instructions.

The main reason I purchased a box was for the economy gains as an Alhambra diesel is never going to be a rocket!! I have to say though its much improved over standard and must have increased the already torquey tdi pd engine as it tries to spin the wheels if you put your foot down when accelerating in 2nd. I fitted this after owning the car for only 500 miles or so and the trip comp long term reading was averaging 48mpg (not bad I thought) . After fitting the box and a few thousand miles its reading 58.4mpg! not believing this figure i've done a few brim to brim fill ups and it actually doing 54mpg so i'm guessing I get around 12% improvement in mpg. I do drive carefully to get this but I still do the speed limits. It's the same as saving 15p a litre now!!!

I can't see why everyone hasn't got one of these fitted as there are no down sides.

Thanks to all at Tdi tuning.

Regards Nick.

Hi Steve,

Just a quick note of appreciation of your excellent service and guidance! The system you provided was spot on and the car is already showing a significant improvement in performance (for a Berlingo that is!), the blue light shines bright and all connections worked perfectly.

I would recommend anybody to your product on customer service alone.

Regards, Terence Potts

My car is a 2010 Volvo XC90 2.4 D5. I fitted the box in less than 10 minutes, found instant power and the car felt so much smoother. I tow a caravan, without the tuning box the XC90 felt sluggish and very underpowered, with the tuning box installed the extra power made towing the caravan much easier, especially on uphill climes. I also visit the fuel station less so quidds in!

Thanks All

Came across TDI as I was looking for a remap for my Seat Leon. I'm glad I didn't get a remap as I am looking to sell my car and get a BMW 330D. I am sending back my CRTD2 box to get a new wiring harness and get the box flash upgraded to suit the 330D when I get it. The customer service I got from TDI is immense. I was a bit confused about the differences between remapping and a tuning box at first, but it all become clear once I had a chat with them. I also got some Xenon Headlamps from TDI they were easy to fit just like the box! Can't wait to fit the box on a BMW.

Cheers,
Paul

Found out about you guys from my mate who had purchased a tuning box for his Range Rover TDV6. We went out for a spin with him and I had to get one! >Spoke to your office where you helped me find the system I needed for my Vauxhall Vectra. As soon as it arrived I plugged the box in and as you know, I am so happy! Never knew I could get so much power and torque out of my car. Keep up the good work, one very pleased customer here.

Harry Murphy

My brother saw your advert in diesel car magazine and he showed me the ad. I thought id give it a go so I ordered on your website along with a Pipercross panel air filter. Fitted the box and air filter to my Corsa in no time, put my foot down and it was instant power. The tuning box is by far the best modification I have ever done. I saw you also do Xenon headlamps and they are a definite buy for the future :)

The thing that struck me about TDI-Tuning is your competitive prices. As a student it's a good grab and I advise anyone to give one of your tuning boxes a go.

Joe Matthews

Hello TDI-Tuning, I want to say how pleased I am with my CRTD2 Tuning Box. My 1.9 JTD 120ps Alfa Romeo 156 is a pleasure to drive again. You systems are excellent and the service you gave to me is first class.

The Power is one thing, but I'm also getting an extra 8 MPG which is very impressive to say the least.

Richard Wilson

I fitted your box after 1000 miles and I have now done 600 miles with it fitted. The difference in performance is immediately apparent particularly with low down pickup. Even though my box is set for absolute max performance as opposed to efficiency, there has been no reduction in my fuel consumption! I averaged 39.2 mpg for the first 1000 miles and since the box went in it is 39.4 mpg

Hi Graham,

Just a quick note to say thank you for the fabulous little tuning box. The improvement in my Mercedes ML280 has been huge. Motorway MPG up from 29 to 35mpg! Massively more powerfully too. Great to see something actually doing what it claims!

Thank you for your help and will be recommending you to others.

Kind regards,
Jeremy Pickup

My car is 2005 MG ZT 135 TDI 50,000 miles - Fitting the Tuner took less than 10 mins - including removing and replacing the engine cover (a simple job, 3 bolts hold it on). The instructions for fitting (and potential fault finding) were very easy to follow.

As soon as I started the engine it sounded smoother and vibrated less. Now almost 1000 miles later the car has been transformed very much smoother - pulls better from low revs, don't need to change gear so much. I am a bit of an 'Eco driver' so I don't thrash it very much, now when I do it appears to accelerate much better and very quick to the legal limit, overtaking I feel more confident.

My mileage is mixed motorway / A roads / country lanes / some town traffic jammed roads. My 'in car' computer was showing long term average 45.5 mpg before fitting - it's now an amazing 55.6 mpg. Will therefore pay for itself in less than 10 months at this rate and I feel I am driving a new more powerful car. Highly recommended!

Dear TDI Tuning

I recently purchased a Renault Laguna 2.0 dCi Diesel Tuning Box Chip from you and I find that I can now engage 5th gear at 30 mph, the 6th gear has a larger range now and I can leave it in 6th at lower speeds. The pick-up in 5th from low revs is better and I did a well travelled route of 160 miles round trip and I achieved a difference of nearly an extra 6 mpg. Not only is the box a great piece of kit but the after sales service is excellent too.

Thank you.

After extensive research into performance enhancing devices for my new Ford Mondeo, I opted for a TDI Tuning CRTD2 system as I had heard through word of mouth that they did what they say on the tin and offer excellent after sales support. This proved to be true. Not only did I get next day service in the supply of the device, the instructions were easy to follow allowing me to install the unit in under 10 minutes. Once installed, this made a huge difference. The pre-programmed setting made the car a different beast altogether! Torque has increased dramatically and power delivery is smooth, throttle response crisp and power all the way to the red line, without the annoying drop off well short of it!!! Traction control is now much needed in the wet!!!

I heartily recommend TDI-Tuning and their products. Coupled with their after sales service, you can't go wrong.

TOP PRODUCT!!!

I recently fitted your tuning box to my Citreon C4 2.0 HDI VTS and what a difference it has made. The torque and power has increased dramatically. I just attended a rolling road day and standard it's 136 Bhp with 246 lbs torque and now it's now 164.9 Bhp with 270.3 lbs torque, amazing!!! Thank you very much. Recommended to anyone.

The support from these guys is second to none. I fitted the tuning box within 2 minutes and the difference is unbelievable no more flooring the pedal trying to get acceleration just touch the pedal and the powers there smoother engine quicker gear change. Thanks guys for your great support and product.

I have used TDI Tuning Boxes on my last 3 cars and have found the product to be both brilliant in what it provides, excellent value for money, and just as importantly, have found the communication and ongoing support provided by the company to be equally outstanding. It is rare to find all these qualities from a single supplier, but this is one company that does just that! If you want a product that will improve your Diesel's performance, improve your MPG and provide a return on your investment, then go to TDI Tuning. Highly Recommended!

Hi Guys,

I have now fitted my CRTD2 and it works a treat! My mpg is up by over 10 mpg which I find astonishing given the other added bonus of power and smoothness it's like driving a new car. I cannot fault your service, the product arrived quickly and the instructions and customer support were spot on. Your company has been a breath of fresh air! I've told all the staff at work about the system so you should be getting a good few orders over the next few weeks/months.

Thanks
Graham

When calling these guys for their help in me getting the most from my car in respect to the performance/torque/economy, their TDI Tuning box did the trick.

Good price and over the moon with what I received.
Willing to take time to explain the smallest detail to help me in the installation.
Very friendly and professional.
What more could you want?

Will definitely buy from these guys again.

I purchased a Tuning-Box from yourselves earlier this week and received it within two days, great! Fitted it today, well impressed. It does exactly as your info suggests. I would have no hesitation in recommending your online store to friends or colleagues.

Yours,

P.S. A very satisfied customer!

Having just purchased and fitted (within 5mins) a TDI-Tuning box for my BMW 120d. I am astonished at how much extra power and torque the tuning box gave the engine.

Average MPG is better, and the slightest push of the accelerator pedel propels you much quicker than without the CRTD2 system installed, enabling me to lift off the accelerator earlier than I would have if I didn't have this installed, therefore enhancing MPG figures. Fabulous product!

Hi TDI Tuning

Received the box and fitted in about 10 minutes, Instantly what a difference. 3rd, 4th, 5th and 6th gear acceleration is noticeably faster with torque available right through the rev band and not just further down. Higher end power above 3500rpm is like night and day in comparison to standard.

The fuel consumption is better, and the engine is running better. All in all I am very pleased I bought it.

Vauxhall Corsa 1.7 CDTI

Just fitted a CRTD system to my 2002 Ford Mondeo TDCI with over 200,000 miles on it with great results, Found the system to give me loads more Power and now burns less fuel! You don't know what you are missing until you get one! TOP PRODUCT!!!

Richard

Wow! This product really works! I was very optimistic about the product but I decided to give it a go and now the torque and bhp is up and I'm finding myself changing gears earlier. Also mpg has vastly improved. I fully recommend it to anyone wanting improved performance and save money.
