Great Service, keep as it is and no improvements needed
I am very satisfied with the TuningBox Fusion, this optimization pack is really prodigious! Serious and very professional company.
I would like to see an improvement in shipping because it got delayed twice
although i ordered product it is yet to be received !! tracking estimates stated it should of arrived by now, prior to order tried calling the local Australian agent no answer or return call
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.
ALL WENT WELL
