tow my 6.0 f350 around on a 3 axel gooseneck with this tune.... oke:Daily driving is one thing. Using the power is another. A stock trans will daily drive on 1000 horse tune. Try and put it to the ground or put a trailer on there and of course the trans is done for.
When at the Drag and Dyno day i never limped the trans, never lifted my foot from the gas.
