Hi, GXPinKC here. I have previously moderated on the GXP Owners Forum, currently I moderate on the Kappa Performance Forum. Used to have a GMR Tune on our 2007 early build 2007 Pontiac Solstice GXP 2.0 L4 fitted with a 5 speed manual transmission. We recently had the dealer remove the tune and "Miss Red Eagle" is now stock.
