hi all<I spoke to couple of tuners today I told them I wanted to do an xforce 3'1/2 inch ehaust system, pwr intercooler and a k+n panel filter,they both said I dont need a custom tune or a capa flash box this is a bit confusing as another tuner told me I WILL need a custom tune.I am new to the turbo scene and want to do it right the first time!to avoid engine failure!!the missus is busting my chops about spending $$$ onthe car,why do you want/need to hot it up,my reply was I'M MALE AND COS I CAN!!please help. thanks.
