I have had an 07 G6 GTP couple of years now and have been back and forth browsing this forum for a couple of years. Just signed up and wanted to say hi. I'm aware of all the mods available and wondering if anyone has gone all out with them. Cams, spacers, manifolds, etc.? I'm only aware of one guy that goes by (linemanbrian) on YouTube. What kind of power are y'all putting down and has anyone got into the sevens in the 1/8th?
