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.
Good communication and double check regarding the motor type of my BMW by TuningBox. Fast delivery of the box. Everything is working fine without any warninglight. Power increase is very noticeable.
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.
