I can program your Ford 6.0 or 6.7, Chevy 6.6, Dodge 6.7.
I offer different levels from Tow mode to extreme performance tunes, also can recalibrate your tire size, shift points on your tranny and remove the rev limeter. Can turn off all the emissions on the truck without removing any of it so you can still pass a visual or YOU can if YOU want to.
Price is $850 for the reflash of your ecm, you will NOT get a tunner, you will NOT be able to change the levels after it is set, you will have a week to decide if the level you choose is the one you want to stay with, after that it will be permanent.
