Everything is very explicit, .... commom knowledge. Connectivity very easy and app also no problem. Engine responds very well, no alterations registered for the moment. Sure to be recommended.
Great Service, keep as it is and no improvements needed
Good Product. I find hard to attached controller somewhere near the dashboard due to lack of double side sticker.
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!
Delivery speed is slow. More than week and nothing happens. If your process is slow you should give clear indication about that fact in confirmation. Setting expectation level is good idea.
