Is anyone still selling any mcc custom tunes for an 08? I’ve written a couple for myself, but I’m no pro. I’m gonna back off my injection timing a bit this weekend as I don’t like so much rattle...

any other tuning advice? I’m only lightly modified. Fully deleted, 5” flo pro straight pipe, afe stage 2 intake, 5.9 intercooler, arp studs...
