TDI-Tuning develops, produces and distributes performance enhancements for cars, trucks, marine and other significant sectors. TDI-Tuning is located in Chelmsford, in the United Kingdom, and has been developing ECU performance modules for over 10 years. Our tuning boxes release up to 40% extra horsepower and torque, and the CRTD4 module also increases fuel economy by up to 20% typically delivering you extra range per 100km. All individual ECU modules are created on TDI-Tunings certified dyno, tailored to each engine code on the market. Potential Gains: 180kW - 221kW 380Nm - 445Nm The 4N20 engine shared in the new Tank 300 & 500 is decent performer when working together with the hybrid powertrain. Combined power figures sit at 255kW & 648Nm, and with a TDI Module the factory engine outputs are increased by 41kW & 65Nm. Both the Tank 300 & 500 are possibly one of the more capable 4x4's currently on sale, and when paired with our TDI Module & Throttle Controller to help regulate all that power, they are simply unstoppable.
