The TD Diesel Tuning Box from TDI-Tuning is a Processor Controlled electronic tuning system. In production since 2004 and with thousands sold, this device has been developed to meet the requirements of your every driving style. Through thorough and intensive testing, this system has been designed and engineered to become almost indestructible! Delivered pre-programmed with our latest software to suit your exact model, this discrete state of the art device packs a lot of punch! 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 latest 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! This Diesel Tuning Box is so flexible; we can even re-program your system for you whenever you change your vehicle in the future. Assuming of course, your next vehicle has the same injection system.

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. Click on the sample video further down the page to see just how quick and easy installation is.

You may be surprised to know that your vehicle was manufactured with 2 different types of injection system. Essentially they both look and operate in the same way, but use different looms. Please click the “Download Documentation” icon further down the page to identify which connector your particular vehicle requires.

All TDI-Tuning Diesel Tuning Boxes come with a full 14 Day Money Back Guarantee and a 3 Year Warranty against manufacturing defects. Full English easy to follow Installation Instructions are provided, and every system is backed up by our 24/7 support.
