nah i dont, i have the stage one turbo upgrade that he is running in my car(new pcm and 577cc injectors) im running 18-19psi and a 75 shot safely all day without tapping out the fuel supply on stock turbo, later on all i need is an upgraded fuel pump. but that car finished is going to be rediculous. i say mid to high 10's with slicks if he is talking about 500-600hp.
