I meant PCV, Power Commander 5, my bad lol. As far as a link just go to powercommander.com and it's the same autotune listed there as well. I just found it easier than searching forums and linking over the net for someone to tune vs pluggin it it, going to a real dyno and letting a tech at the dealership who is trained to tune with PCV's set it up for me. After that the autotune keeps the tune right where you want it!
