dude, im sorry mberndt, but you are a fucking idiot! There are experts here for a reason. that reason is to help idiots like you to have a more RELIABLE street car. tuning is not just to make the MAX amount of power, but its to make sure everything is in proper working order. There is nothing better you can do for your car than tune it. whether you have minor bolt-ons or a T3/Gt40 blowzilla .63 a/r turbo setup. You seem to be fine with it "running a little lean" so let it be. well my friend, your gonna have serious issues down the road and remember it when you blew these guys off when they provided some seriously good information to you. Youd be better off sticking your head up your exhaust pipe cuz thats where you belong. kiss my ass. Thank you to all the guys that provided good info! I found it very interesting and learned some good stuff.
