Here are the results after reprogramming of the engine control unit. We ensure the tolerances set by the manufacturer for the engine and gearbox are not exceeded.

Stage 2 is a tuning of the engine management which takes into account different installed parts. In the case of a petrol engine, this is an exhaust / downpipe change with sport catalyst. An intercooler and / or air filter can complement the exhaust / downpipe.

E85 Flex fuel : 550HP 693Nm

The E85 flex-fuel tuning allows your vehicle to run on two types of fuel: bio-ethanol, gasoline or both fuels simultaneously. Further to the optimization of the engine mapping, your engine will adapt its operation according to the amount of bio-ethanol injected. Do not hesitate to contact us for more information.
When the E85 conversion is not possible at the level of engine mapping, an additional flex-fuel box can be offered as an option.

E85 Flex + : 565HP 713Nm

The E85 flex + preparation combines reprogramming and E85 flex-fuel conversion. You will therefore recover a more efficient vehicle that can run on E85 fuel or gasoline. Do not hesitate to contact us for more information.
In some cases, flex-fuel conversion can not be combined with standard reprogramming.

Recent gearboxes allow quick gearshifting but does not deliver its full potential so far. With the reprogramming we are working on several parameters:

  • Decreased gear change time
  • Increasing maximum engine speed (rpm/min)
  • Increasing the maximum torque
  • Removing kick-down (if available)
  • Improving responsiveness

Air filter BMC Logo

What does the sports air filter do? For good combustion, the fuel and air must be free of impurities. By its design, the sports air filter improves the performance of your vehicle by optimising the flow of air to the engine. Unlike a conventional paper air filter, the sports air filter is made of cotton and can be washed.

Compressor pulley +35HP / +30Nm

Unlike a turbo-charged engine, where the turbo is driven by the exhaust gases, a compressor is driven directly by a belt. In order to increase engine performance, it is possible to modify the compressor pulley by using a smaller pulley (10 to 17% maximum) which will make the compressor turn faster and therefore generate more pressure.

Power curve

The role of the ShifTech motor mechanic is to enhance the settings while trying to obtain the most homogeneous and coherent curve possible. The power and torque curves for the preparation of your vehicle are placed in good hands and discussed individually.

Each SHIFTECH reprogramming operation is preceded and succeeded by putting the vehicle on a Cartec 4x4 1,200 HP dynamometer. The dynamometer serves two purposes:

  • to measure accurately the torque and power the vehicle develops before and after reprogramming;
  • to detect any problems with the vehicle: seized turbo, torque too high, clogged airflow metre or air filter.

The test bench is equipped with a 60,000 m³/h fan in order to replicate road conditions as closely as possible.


We offer free updates of the mapping and to return the vehicle to its original state if it’s going to be sold. These updates are effectives for 5 years. We guarantee a power and torque increase after reprogramming, provided the engine is in good condition and servicing has been carried out at the right time. If your engine management system is updated by your dealer, we will reprogramme it free of charge based on the update.


In order to provide the best conditions for waiting, each ShifTech centre has a waiting room equipped with WiFi, magazines and a TV. Drinks are also on offer. If you prefer, you can leave your vehicle in the morning and collect it again at the end of the day.
