0 to 80ish pull with the 93 Performance tune from jay green. Truck was in 2 wheel drive no brake torquing , traction control off. Truck pulls real good and the trans shifts are firmed up and smooth as well. Love the way it drives now.The truck is also sitting on 33 inch nitto ridge grappler tires as well. Jay is real professional and had the tunes to me in one day. Awesome product would definitely recommend this to anyone.
