The CRTD2 Diesel Tuning Box from TDI-Tuning is an advanced Micro-Processor Controlled, Digitally Programmed, Multi-Mapped electronic tuning system. Currently our flagship product, this device has been designed and engineered to meet the requirements of your every driving style. Vehicles fitted with a DPF (Diesel Particulate Filter) are no trouble for this system, as the CRTD2 boasts high performance processors, which are used to enable real-time processing without affecting the internal protection function. Delivered pre-programmed with our latest software to suit your exact model and pre-loaded with 32 maps to choose from, this discrete state of the art device packs a lot of punch! The CRTD2 can be adjusted yourself if you wish by means of simply moving a series of jumpers on the back of the tuning box to select one of the 32 fuel map programs which takes seconds to complete. Adjustment is a key design feature of the CRTD2 to ensure you have full flexibility over the power gains you achieve. However this is completely optional as the system is dispatched fully configured. Manufactured exclusively for TDI-Tuning and encased in our own anodised aluminium, durable weather resistant housing, this system is as strong as it is powerful.

Before this system was developed, we asked thousands of our customers from all around the world, what they would like to see in their next generation of TDI-Tuning Diesel Tuning Box. Well we are pleased to say that we have listened, and we have delivered! Because the CRTD2 is effectively a computer, our software programmers have complete flexibility on how they program each vehicle map. This Diesel Tuning Box is so flexible, we can even re-program your system for you whenever you change your vehicle in the future.

Installation and removal is exceptionally straight forward. This system has been engineered to ensure that even customers with no mechanical experience can install this system themselves in under 5 minutes. To make things even easier, this system is completely "Plug & Play" ensuring there are absolutely no cables to be cut. We also only use Genuine OEM connectors to guarantee easy installation. View the video further down the page to see just how quick and easy installation is.
