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