hey i am starting to upgrade my grand prix, i now have mangaflow mufflers, K&N CAI, and new plugs. I still want to do more to my car, what would you guys recommend for a good performance upgrade?? Preferably safe too. I have heard about getting the PCM tuned, but im kind of a noob, so i wouldnt be able to do that, are there any special places to go for that? Thanks

+1 on the sticky bluegtp, just got my first gp and read your sticky and saved about 20 or so not needed threads! Very informative and detailed and trust me, i've been told throw a pulley on it and drag it! So i'm glad i read all that!
