OK so I have the 08 stock cobalt 2.4L engine non TC, and I've been looking at performance chips to lift off some of the restrictions like the rev limiter and maybe get SOME hp gains but i don't know which one to get most of the ones i find are for a TC or SC cobalts and does anyone if i can run em?? i found some from ZZP..

thanks.

 

Check out trifecta tuning.

 

they say those dont work... yeah they also say trifecta or HP tuners.... i still am not sure myself... i run all stock pretty much, cept the K&N drop in filter... but im also not sure where i want to go in terms of performance.. ha i may just give up.

 

Hp tuners or Trifecta is the way to go for GM. Seeing as i have a Chrysler, i went with Diablo sport, its like HP tuners, except its a bigger pain in the ass.

 

haha i just got off that site and they didnt seem that helpful..

 

ok so what if i buy there product it allows me to do... pretty much tune my own engine?? thats what i get from it.

 

HP tuners, have a tuner do it, do not do it yourself.... you can buy the tuning software, or pay $100 for credits for your vin so the tuner can access it, dyno tunes are roughly 350-450 depending on the tuner/ work required for your setup

 

i have the stage 2 jet chip. i don't feel any difference, but my afrs are less rich at wot. high 11's low 12's

 

trifecta

 

trifecta is the best way to go as for tuning.

 

ive heard HP was good for autos...
