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.
Great customer support!
I am very satisfied with the TuningBox Fusion, this optimization pack is really prodigious! Serious and very professional company.
