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.
Good Product. I find hard to attached controller somewhere near the dashboard due to lack of double side sticker.
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
Everything is working fine.
