Hey guys picked up a 08 hhr ss auto and after bring home figured out it was pushing @23psi. Is there a way to find out if its a gm1 tune or etc

 

Cool, 23 scoots don't it ?? It has to have a tune stock is 14lb. This is a terrible pic but it should work. Look for the sensor, if yours has the blue/white bosch sticker, you have stg1. If it doesn't look like that and has two screws holding it on (they throw out one for the bosch) you have an aftermarket tune, there are lots of guys who will know more than me there. I can tell you mine Trifecta has a trigger on the cruse control botton, others have put the trigger on the traction control button, you could try some button pushing, might be a clue.

 

kool thanks
