So u cobalt guys have been around a lot longer so looking to your expertise for which meth kit to run. Snow has the same 20012 part number for both cars so assume aem and others that list for cobalt SS will work on ats. Stage 2 seems like a good hp level so now just don't want to over spend on it going with something I don't need or a company that is just more proud of a sticker or name so charges way more for same product as another company. My 115-120 iat logs last night here in north Florida is pulling 5 degrees timing and killing the car and going to get worse so only option until someone makes a good front mount for this car.
