ATP EFILive Duramax Custom Single Tune by "Idaho Rob"
From mild to wild we have you covered.
You must have access to a FlashScan V2 or ATPTrucks AutoCal to flash this tune into your truck.
If you have an aftermarket fuel tank include size of tank in Cab & Bed Style field.
If you need a VIN License, we have them available here.
Rob will not build smoke or lope tunes.
