Good Product. I find hard to attached controller somewhere near the dashboard due to lack of double side sticker.
Great Service, keep as it is and no improvements needed
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.
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.
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.
You should send a tracking number. I ordered as express and it took 10 days to arrive and i couldnt track it.
