チューニングボックスの仕組み

Typically, engine power output is restricted by 20-40% below its full potential. Most manufacturers develop one engine and then electronically restrict it to comply with regulations, fuel grades, and climates in various countries.
Engines have the potential for better performance in terms of both power and cost.
TDI Tuning has been developing pioneering solutions to this problem for over a decade.
Our tuning boxes are designed to unleash this inherent power and provide comfortable support for your daily driving.

Increased Performance

Unlock the potential of your engine. Our tuning boxes can increase horsepower and torque by up to 40%. The CRTD4 can also improve fuel efficiency by up to 20%, typically resulting in a 4-6 MPG improvement.

Customization

You will experience how the TDI Tuning box understands your engine. Every tuning box is designed by our specialist technical team to work seamlessly with your vehicle.

Reversible to Stock

TDI Tuning boxes do not overwrite the engine's ECU, so once the tuning box is removed, the vehicle returns to its original condition without leaving any trace on the vehicle's ECU.

Power increase or cost-effectiveness increase?
With the TDI Tuning App, you can control it from the driver's seat. Instantly change engine performance and adapt your car to any situation.
