not much you can do, everything is Electrically controlled on these cars. I'd say the most you could do is simple bolt on stuff, but if that don't work, a tune might, but no promises.

As said above bolt ons will help, but if you have an automatice you wil still have lag as you have to wait for the torque converter to spool up also.

a light weight flywheel always helps throttle response. but that is a little pricy

Air box mod or intake make a difference other then that.
2.4 TB and manifold and a tune.

I have the 2.2 vvt LAP (2009-10MY) and sure nuf lagging throttle response. But after a half second it does really go and I didn't know about it lol.

From what I hear the Trifecta tune (the best from most here) is undetectable to GM. Is that true? If possable i'll score a spare PCM.
