Installing a Whipple kit on my 2010 GT500 in a few days, been reading the other F150 Whipple thread, wondering if I should use the Whipple tune that comes with the kit, or start from factory (Ford) tune, & go from there?
If HPTuners will read the Whipple tune, that would be ideal, so if their tune needs tweaking, I could simply change a few things & go, but some say HPTuners won't even read the tune, some say they can read it no problem, anyone have any input?
