STR Diesel Tuning & Tunit Kits Norwich, Norfolk

What is a Tunit?

The Tunit is an externally installed performance product suitable for all modern diesel engines. Tunit is designed to improve power, torque and efficiency, without compromising fuel economy. In most cases applications will achieve a 7-10% saving on fuel. It is retro-fit and will not interfere with original equipment or the manufacturers warranties. Installation is usually a swift process. Thanks to Tunit, diesel tuning is possible to increase the performance of all modern diesel vehicles by up to 30%.

You may appreciate your diesel vehicle for its fuel economy, but you find it a little lacking in power! Or maybe you just want that bit of extra get up and go. The Tunit has the solution! This innovative and clever device provides a substantial increase in power and torque for the amateur or serious performance user.

How it Works?

All Tunits are specifically designed to achieve enhanced diesel performance by modifying the fuel injection parameters and only by the careful interplay of these values and characteristics can the optimum performance of your engine be achieved. The turbo boost pressure is not directly altered (on turbo models) by the Tunit and is only increased via the natural increase in exhaust gases provided by the increased performance. The design and development of the Tunit has come about by the collaboration of some of the top minds in Europe and is the latest and most advanced device available on the market today.

What is achieved ?

Immediately the increased power and torque can be felt. The throttle response is improved and particularly low and mid range torque is vastly improved, making the overall performance of the vehicle completely different.

When carrying loads and/or towing, the extra power is a also great advantage. The overall drive becomes more pleasurable and the engine in most instances runs smoother.

In independent tests and trials, results of 7-10% extra better fuel economy have been achieved. This obviously varies from vehicle to vehicle and application.
