i just got a predator programmer that was on a tow truck for free. It was on his 03 6.0. What do i have to do to be able to use it on my dads 06 6.0? Is it a good programmer? i know hes blown a head gasket, but he beats the **** out of his and uses it to pull out his triaxle wreckers. He's gone through 3 headgaskets, 4 trannys, and 2 rear ends.
