I have a 2.2 that I'm supercharging and can't seem to find a place that can tune my ecm. Does anybody know where I can get this done or if I get the HP Tuner file for the 2.0 can it be used to tune my 2.2 ECM. Thanks for any help

lawlz sorry man but the only way to tune is trifecta performance for the most part
unless you have an 07 then you can use LS2

You posted in the TC section but I believe Vince at Trifecta Performance can help you out.

No HPT does not support the 2.2L in the cobalt I think the only ones that do support your car is terifica.

Wow thanks for all the quick responses guys I appreciate it
