Hey everyone so I been working on a little project on my pontiac g6 gxp 3.6 ly7 vin 7 opt 8 .. I'm ordering the mace performace cams with there timing chains kit.. now it says i need a proper tune after that .. at the same time I'm in the process of port and polishing my cylinder heads... now I heard with hp tuner i cam tune my car but I don't know how to do that. Is there any shops around New York or at least within 200 to 300 miles that can perform the tune for me? Or any type of advise that I should go about tuning the g6.. thank you for anyone help on this topic. be safe all
