What can I do to tune my L61 motor? I'm not sure if I can change to an '07 computer or if that's even possible, since they are programable and mine isn't. JET sells a Stage 2 chip for it, but I imagine it's just a piggy back set-up. Has anyone used the JET chip yet? And if so what is programmable on it, and how well did it work? All answers are appreciated. Thanks.

 

trifecta.. unless you can somehow swap the 07 comp then you can use ls2edit

 

What year Cobalt do you have?
