At 10psi I have full boost right when I hit 2nd. It's nothing a EBC wouldn't take care of though. I know a 2-step would I would probably be at 5psi at launch. Let me know if you can find one that's under $200. My rpms on the freeway are about 2000rpm at 85mph. And 1800rpm at 75mph.

I hear good things about the LS7 clutch too, but I don't know how it would behave behind a 5000lb truck.
