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
Instructions for my vehicle were not accurate for both the Pedal Tune and ECU Tuning Box. Pls check your diagrams for the BMW X5 E70, N63 engine!
When I ordered, there was no stock for the particular car I owned. I waited one week for the stock but had to write in to check what was the status. However, I must say the response was good.
I am very satisfied with the TuningBox Fusion, this optimization pack is really prodigious! Serious and very professional company.
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.
