Dyno numbers.
I recently had my truck dynoed truck has 3.42s an lq9 with a tbss intake, 862s with ferrea 2.02 intake and 1.57 exh valves, titanium retainers, multi angle valve job.. milled .030/ now have a 58cc combustion chamber , also has a tune. Truck is 4wd with a 4l80 an silvy ss rims 275/55/20. Truck made 283rwhp an 351ft lbs. I thought the numbers are kinda low was wondering what yall thought. I believe it was a dynamics dyno, I can make sure later today. Thanks for any thoughts.

Also that dyno works best for turbo applications. It reads lower than most other dynos out there since its a load bearing type.
I only put down something like 350hp on one with a turbo lq4 on 6psi.

tq looks ok, but hp numbers looks only a little better then a stock 5.3 Even with the 20's and 80, I would have though it should make more. What kinda times have you went in the 1/4?

It hasn't ran the 1/4 since I got the 4wd working. I did a 15.3 at 93.8 with a 2.45 60ft lol, that was 2wd easing off the line so I wouldn't spin and before the heads an tbss intake. I would like to be around a 13.5 now, think I am?

Some thing is mix matched or the tune is just horrible. That truck with a stock 6.0 should go in the 14's by it self. The obs trucks are lighter then the newer ones also. Hell my truck in the sig went high 14's with a hypertech, lt's, cold air, with the 4.8.
