Good Product. I find hard to attached controller somewhere near the dashboard due to lack of double side sticker.
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!
I am very satisfied with the TuningBox Fusion, this optimization pack is really prodigious! Serious and very professional company.
