That is crap man, post the guys name on the forum so no1 else goes to this bloke. and then take a dump in his letter box!!
If you live in Bunbury, have you thought about taking your car to Kwinana Performance? It mite be a 90 minute drive but they are guns and have kalmaker software. The tune will cost you around 900 but by the sounds of things, thats a small price to pay to have your pride and joy back and better then ever.
