Inexpensive chip-type devices won't do anything for you. You can spend $2000 to $3000 in Cold air intakes, header, cat delete, exhaust and a custom/canned ecm tune and still see only 20 - 25 hp increase on a 2.4.I am looking at buying a 2007 Solstice with a 2.4 engine and a manual gear box. I am cheap, so what can I do to boost the ponies? Specifically, would any JETCHIP devices help? Also, what is the best performing cold air intake for this engine? Thanks!
