LQ9 cammed dyno 314hp/332tq
Got the truck dynoed today. Lq9 with 317's, 228/230 cam @ .585 lift 112LSA, long tubes into 3" Y pipe, stock exhaust back. 5" intake into stock TB and manifold. Flexfuel injectors on stock fuel pump. Tuned on 93. Ran in 3rd gear through a built 4l60e through 3.73 gears. 20" wheels from a new truck with 285's. E-fans. Thought it would make more on a DynoJet. Any thoughts based on the graph?

Easy to cut off or unbolt the muffler and go for a rip just to see. The plumbing can support a lot, and long tubes/ no cats already clears that restriction
can try it the the y pipe disconnected from the rest of the exhaust too, eliminate the tubing size if you're worried
What were you expecting? Stock 6.0s make ~300, so imo you aren't far off from what I would have expected. If you can rev it out further, you'll make more power. Tq*RPM/5252. Get more RPM in it 🤘🏻
Edit: sorry I thought I saw you were making 391, not 314. My bad; exhaust removal still applies

Was hoping for 340-350. I will give that a shot.
Here's a thread with from a guy with a smaller cam than mine, 3.5" exhaust instead of mine and a fipk intake, made ~50hp more than me. Seems like a big difference for just an intake and 1.25" larger exhaust, no?
