am very pleased with the whole process. You have to watch the transport package, the parcel has got into my hands in poor condition TUNE PEDAL outside the box and the bag torn.
all very well
Everything is working fine.
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!
