How do i make my 2000 pontiac grand prix gt faster? like, i have exhaust and intake. what mopre? a chip?

i would suggest reading around clubgp.com or gpona.com. It all depends on how much money you are looking to spend and how fast you want to go. http://www.clubgp.com/newforum/tt.asp?appid=6 that is a good place to start since your engine is an L36. Don't put a "chip" in your car-its a joke...instead you will have to either buy an aftermarket PCM or a tuner. what exhaust mods do you have? is your u-bend replaced? ported exhaust manifolds, headers, downpipe? if you are looking to build a fast car and have the resources, turbo, intercooler, cam, rockers, etc are all options. if you just want your car a little quicker you could put rockers or a cam in, supercharge it, etc Scanning for knock retard is always a good idea. Take a look around one of the forums above-lots of good information on them. Also, two reputable 3800 dealers are zzperformance.com and wbodystore.com. you can look around their online stores and check out prices and what they offer.
