So when i bought my car i purchased the GM warranty, but some time after that i found out that the car already came with a few mods (aftermarket headers, exhaust, motor mounts, pcm calibration, new fuel injection..) then i installed a K&N intake...so i was wondering...wouldnt this completely void the warranty? n when taking the car for a check up the told me that the car isnt running as it should, so they recomended me doing a tune... i need some expert's advice!
one more thing...my car is a 2.4 would all this mods make a major improvement on the car?
how fast could the car be really running?

the words gm and warranty should never be used in the same sentence without the word bull****
