2500hd 6.0 s480 turbo engine going back in trick manifold

[@RocSteadyNY]

Any mods to the 4l80e?

None yet. Just a 3600 stall converter, and this turbo spools up great. I'm only on 7lbs wastegate and it lights the tires up with ease. Doing 650hp to the tire on wastegate and 920hp @ 15lbs. Once I figure out the traction issues there is no since in turning it up.
