Don't waste your time with stage 3, just get a smaller pulley and a custom tune. Stage 3 locks your PCM so you can't tune it. So pretty much after stage 3 no warranty, no AC, and no more tuning.

 

gm owns up to the reality that the stage 3 system is pushing the limits on the ecotec engine. you would be better off going aftermarket, creating more power safely on the stock internals. besides srt-4's aren't that much to brag about besides their power potential. c'mon, they couldn't even make it look different than the regular neon!
