Finally got a dyno tune for my truck
Did a 6.0/80e swap in my truck but had to rebuild the engine, finally got everything back together and broken in!
Specs on the engine: '02 LQ4 that I went .005 overbore with forged flat-top pistons w/Total Seal rings and forged i-beam rods w/ARP bolts, stock crank checked out ok, used King XP bearings and stock cam. Built by RPM.
Heads are stock 317's with a valve-job, LS6 springs, Comp trunnion upgrade, chromoly pushrods, GM hi-volume oil pump, LS2 timing chain/gears, and LS7 lifters.
Stock '99 5.3 intake/throttle body and stock exhaust manifolds/y-pipe into a flowmaster 70 series dumped at the axle.
Trans is a Jake's stage 2 80e with a stock re-man torque converter.
It made 317 hp and 362 ft-lb. We went on the safe side of the tune, I was surprised by the numbers, makes some good torque and is fun to drive
Might do a mild cam after my wallet recovers.
RPM did a great job on the tune, much better than the mail-order I had from Nelson, shifts nice on the street with very smooth power delivery.
This was the final pull
Got a vid of the 2nd or 3rd run can't remember
