Hoping someone here can help me. I have an '08 Solstice GXP. I have Solo Race exhaust, high flow cat and a CAI. I also have a tune, but don't know who or what tune I have. It's not GMPP....I do know that. My issue is this, when my car is cold (<150 degrees roughly) it falls flat on its face when I go 1/2 throttle or more. The boost does go up to 20psi at that point, but the revs won't really go past 3000. Is this a safety feature in the tune? Am I having some sort of internal issues? Like no compression in the engine until it gets warmer? I also noticed that the exhaust does get loud so the boost is coming out the back I would assume. Is this something I'm going to have to live with?? I live in MI and planned on driving it in the winter on nicer days....but if its going to act up like this, I can't take a chance. I can't even pull out in traffic when its cold for fear it won't go! Any help is appreciated!
