dantwomey Posted January 16, 2005 Report Share Posted January 16, 2005 I just bought an 03 SS and I have the upgrade bug. What can I expect from some easy beginner level mods? I was thinking of starting with PCMforless, change to a K&N filter, and pulleys. Any feedback would be appreciated. Regards, Dan Link to comment Share on other sites More sharing options...
cadowns Posted January 17, 2005 Report Share Posted January 17, 2005 A good Tune can give about 30 hp. Be carful about using the underdrive pullies, as some have had Knock problems. Just do some seaching on here. CD Link to comment Share on other sites More sharing options...
zippy Posted January 17, 2005 Report Share Posted January 17, 2005 you should see a noticable gain just in the programming alone. overall it's a nice performance boost and about .4 in the quarter with all 3 mods. Link to comment Share on other sites More sharing options...
