Ok, I'm stuck at the moment. I've got an 02 GT with the K&N fipk, a 70mm ford racing throttle body, and the 40 series flowmaster mufflers. I've been searching through the recommended upgrade posts but I haven't been able to make up my mind on anything. I've got about 300 dollars set aside for my car right now, and I'm just wondering if there's anything worth getting for the $. I'm pretty much looking for any kind of suggestion. I'm not a total noob, but a lot of you know a hell of a lot more about this kind of stuff than I do
...I'm pretty much looking at minimal hp/torque gains since I can't spend all that much
, and I was thinking pulley's maybe? or the mac prochamber, but then I started to read about how they didn't pass emissions, and that's no good for me (I could be wrong though...) Anyways, any suggestions would really help, and if there isn't anything worth getting for the kind of money, just let me know.
