help with performance please

ok so i am just getting my 2004 GTO

it has the twin plate Exedy clutch, K&N cold air intake, B&M short shifter, borla true dual exhaust, eibach lowering springs, adjustable struts, and alot of body mods....

i was just wondering what would be a good next move for more power/performance....chip, cam.....

i am not really smart when it comes to these kind of engines, this is my first V8 i used to be a tuner guy (had a chevy cobalt)

looking to get this car with some good track times


thanks guys
Ryan

If your on a budget a good tune will make a noticable differance in power. If you realy want to improve your times, go for headers, a cam, then a tune.

Headers and a tune. Get the rear fenders rolled, which should compliment the body kit and get wider rear tires. There really isn't a chip for the car, but there are handheld tuners. I don't have any experience with them, but I do know that a dyno tne set-up custom for your car will really wake it up.

yeah i saw a set of rims for it i want, they are 18x8 in the front and 19x9.5 in the rear.... but i will most likely have to roll the fenders... how they go about doing that....

i also saw a set of rims that were 18"s but the rear were 10" wide... would that even work?

yeah i think i am gonna get a set of long tube headers asap, and a throttle body..... then the cam and tune at the same time.

what cams would be recamended? looking for a lot of power and i like a good lumpy idle.

I need help....I have store credit to a speed shop for about 350 dollars since I returned an item I didn't need anymore. I want to buy a bigger throttle body for my 2004 GTO, but my car has has been tuned and I don't know if putting a bigger throttle body on it will affect my tune in anyway. Will I lose hp do to the way the car is setup or will my car gain hp. Any help would be great. Also what is the stock fuel injector size on an 2004 GTO.
