can I put a performance chip on my 2007 cobalt 2.2 liter engine?
If you can find one. I doubt you would notice the difference and you probably won't pass smog inspection if you do install one.
Try a ignition upgrade. Internal & external distributor Ignition control module.
Visit ZZ Performance and see what they have for that engine.
