This way your acceleration is much more direct. This pedal box is ideal to pass vehicles easily.
all very well
Instructions for DIY installation should be more detailled and specific for every single car model. Simple things as intake air filter position makes wiring more difficult in my fabia than in volks.
Instructions for my vehicle were not accurate for both the Pedal Tune and ECU Tuning Box. Pls check your diagrams for the BMW X5 E70, N63 engine!
Everything is working fine.
Great customer support!
