Well i was lucky enough to have the juice for an hour. A fellow duramaxer installed it on my truck at the Northeast Ct get together yesterday. All I can say is holy schmokes. My truck never smoked or squealed like that before. We went through all the stages and it was like I was driving a race car. I was even able to smoke the tires, and on a dually thats excitement. Thanks for letting me use the juice. It was nice to meet ya at the Get Together. Next time we put the juice to my truck it stays!
