tranny tuning maybe?

can't wait, i seen what efi live can do on a duramax. i would love to have my truck run clean with little to no smoke.

have you already selected all the beta testers? i would love a little more tuning, i picked up 80hp by switching to smarty ssr and tuning it.

can tunes be switched on the fly?

put me on the waiting list.

can't wait to see more updates. love to see a 5 switch. put me on the waiting list
