I had my Nelson tune set up for all of that plus the trans go hd-2 trans kit and the Corvette servos. All the work is done and boy does she hit gears in a good way now. I can chirp second with my 275/60/17 tires with my 4.8L. Just be easy on your truck and don't drive it like you stole it all the time and it will hold up. Gears and a converter is next on the list for me, and I am sure it will be even better. Good luck on your project...... Mark
