Very recently bought a 07 GXP with very low Milage . Few questions,runs great. Has a noise on startup for about one minute then a chirp and it goes away. Also this has a KN turbo cold air intake and a magnaflow exhaust installed by previous owner. Really pulls great, I never drove a Turbo Solstice before just a 2.4 . Has a chirp noise from engine when shifting ,no not from the wheels . I have been told that it is the waste gate because I have the cold air intake and if I had the full old air cleaner it wouldn't be as noticeable. Any feedback?
