I have an 06 gto that's pretty much stock. im thinking about buying a thumper cam for it this winter. I'D also like to get a tunner for it but I have no clue what one to get or what kinda power increase ill get with one. if any one could help me with some info on it I would appreciate it. im sorry if this isn't how you post stuff on here, this is my first time on a forum site.
