Had my 5.3 s10 swap dyno'd and made 359 Rwhp and 335rwtq. Power fell off early, thinking maybe exhaust is restricting?
Combo;
2005 5.3
4.8 pistons
.20 milled 706 heads, no porting
Torquer V2 Cam
Shorty headers
No cats, y-pipe to 3in exhaust and Borla race bullet
Stock 2005 intake and throttle body
3200 FTI Stall
8.8 3.73 Rear
Heavy 17x11 replica rear wheels

Dyno'd in 2nd gear, so should be a little higher if dyno'd in 3rd. Is it about 5% on average?

I had always thought 2nd gear pull generally reads a bit higher not the other way around, but not by much regardless.

I see it making 380 wheel.

Yes, stock truck intake, as in no porting and not an upgrade to a nnbs/tbss intake.

Tuner was worried about driveshaft speed

Longtubes would help alot!

Shorty headers are not much better than stock manifolds. Could easily be a 380rwhp truck with some good exhaust.
