Update: True-Trac is in and I love it. It's nice knowing the rear is actually trying to move the truck foward.
Also, even though i'm 600+ miles away from home this week, my friends talked me into dyno'in the heavy chevy. Made three pulls.
Couple issues kept me from better numbers. These include a maxed wastegate spring at 10psi on the dyno. Not sure why, but I can get 11-12 on the streets, but only 10psi on rollers. Also had some HPtuners problems. Truck was shutting down at 130MPH (5700rpms) not sure why since my fuel cut is set at 6300. The throttle % just closes up though, so I have to figure that out.
First pull was in third gear to see how it looked.
Netted: 490HP/469TQ
Then 4th Gear:
Second pull: 506/525TQ
Third: 528/528
Over all, very happy with the truck at this boost level. I would have been more then happy though to take it to 15psi area if the wastegate would have played along. Maybe next time
