TurbochargedBerserker Posted August 5, 2004 Report Share Posted August 5, 2004 Go for a custom tune and some tranny work to start. Then you can decide which direction you're going. Hold off on the exhaust until you rule out a turbo as its kind of wasting money if you go that way. Link to comment Share on other sites More sharing options...
deezel Posted August 5, 2004 Report Share Posted August 5, 2004 Custom tune, electric fans, shift kit, trailblazer converter. All should be warranty-friendly mods. And good for future upgrades. Link to comment Share on other sites More sharing options...
