im wanting to run the mcrat 500 race tune on my truck and im wondering what do i need to do to my tranny to were it will hold the power and not mess anything up. i pull with the truck and i wanna race the truck whenever i get tranny beefed up and also who knows may try to do a little sled pulling maybe though. thanks

Stage lV kit and a triple disc converter, a stage 3 kit would probably do fine but a stage lV does'nt cost much more.

is their any difference between the PPE stage IV and the suncoast stage IV like price and durability
