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.
Fast delivery, had an initial issue with one of the connections, but 1 phone call and a technical email later all resolved., I have tried racechip previously but I am more impressed with this company.
You should send a tracking number. I ordered as express and it took 10 days to arrive and i couldnt track it.
I would recomend to have whats app, sometimes I need to talk online and its easir than emails
