Want to get better performance.

**GMCARS4LIFE** · 07-18-2011

Hey guys I recently went to the track with my 02 gtp coupe with open cone intake and ran 14.8 in the 1/4mile. I don't want to do anything to drastic but i would like to get that down to around a 14.2-14.5. What mods would you guys recommend? I am thinking a 3" DP and a tuned pcm and 180t-stat. Do you guys think that would do the trick or would I need to do something else. Also what pcm would you guys recommend?

Skip the DP and get headers instead, Speed Daddy headers are a tad more than most of the 3" downpipes available on the market, and yeah defiantly a tune. You probably wont notice much of a difference in performance with just headers and a tune but then again you might depends on the tune.
