Diesel Tuning Boxes - Audi, BMW, Volkswagen

Welcome to DTUK Performance and thank you for considering us as your tuner of choice for engine tuning. We specialise in performance chip tuning boxes for a huge range of vehicles. DTUK Petrol, Hybrid and Diesel Car Tuning Boxes are manufactured in a state-of-the-art facility in Germany using high quality components and connections from Original Equipment Manufacturers (OEM) so that they match exactly with the existing engine connections in your vehicle. Almost all applications are ‘plug & play’ using our detailed, colour installation guides allowing even inexperienced home mechanics to install the system and increase performance & economy on their own driveway in a matter of minutes. Simply plug in, drive and enjoy, safe in the knowledge that your vehicle warranty is intact. Once fitted our car tuning box to your car, you can expect up to 40% more power and torque, sometimes even more, depending on application. Search for your vehicle to see more detail on the figures you can expect. Check out our Rolling Road page to see real world, customer supplied evidence of our results. You will also benefit from an engine that now runs more smoothly and efficiently. Efficiency gains of up to 20% are achievable for most applications. “Flat spots” in acceleration will virtually disappear. For vehicles that still suffer with “lag” on initial acceleration you may also want to consider our PedalBox system that improves throttle response on drive-by-wire vehicles. DTUK Petrol and Diesel Car Tuning Chips (for the techie amongst you) sit between the vehicle’s ECU and engine to control the fuel injector system, turbo and more using sensors on the common rail or injectors and a range of other sensors depending on application. Check out the “Products” page for more information. This means, unlike other tuning options, that we do not interfere directly with the ECU or break any factory seals so avoid invalidating your warranty.


The majority of our systems can be fitted by the average customer in less than half an hour, many in 5-10 minutes. All come with full colour fitting instructions and first class telephone customer support. Be very wary of anyone who can ‘flash’ a remap to your car in that period of time as it is most likely a generic map downloaded off the internet and loaded from their laptop.

All our car tuning boxes offer a range of adjustability not available with a remap. As each vehicle is built to a manufacturing tolerance, no two are the same. The same is true of each driver. As such, adjustability is required so that the customer can tailor the system to their vehicle and driving style.

Many engines are shared between manufacturers, as are components and technologies. As such, most DTUK tuning systems are transferrable between a variety of vehicles, often only requiring a software change (free to existing customers) or a change of loom (charged at a trade price to existing customers). Alternatively, if nothing can be done to transfer an existing system to a new application, an existing customer can purchase a suitable system at a trade price.

DTUK tuning boxes are well known across internet forums and popular auction sites. As such they command a healthy resale value should you choose to sell the system on when you change vehicle, whereas a remap or soldered chip would stay with the vehicle and your investment would be lost.

A remap can also cause you issues should your vehicle visit a garage, dealership or be subject to a warranty repair or recall. Firstly, It is standard practice in many workshops to automatically perform a full software update on any modern vehicle that goes in for work. This update is highly likely to overwrite any remap (aftermarket software) installed on the vehicle. Secondly, the presence of a remap or the physical alterations (breaking the seal on a factory ECU, etc) required to install a chip will immediately invalidate any manufacturer or aftermarket warranty. As a tuning box does not involve touching the vehicles ecu, you can simply unplug the DTUK box and the car reverts back to original without leaving any physical oR electronic trace. Once reinstalled you can take advantage of the additional power and torque instantly

Just a little something to consider before you make a purchase.
