Youre trying to argue semantics maybe but the torque falling off and hp also are a pretty big deal.
The tuning looks somewhat bad as well. The lines should not be that bad.

tech@WS6store. I'm not arguing anything. Just thought I'd give my thoughts, and some facts, to the OP. To try and maybe help out. Sorry if you thought I was here to argue. It's all you.
Here's my results for comparison, granted it's an LS6 (C5Z - SSHT cam, 1-3/4 LTs, LS6 manifold, stock LS6 heads). HP peaked around 6,260 for me and the power carries a lot better than your graph so I agree something is up.

Hello OP. Just to give my opinion, I don't think your graph is too far from the other Streetsweeper HT cam graph. Your dyno graph is on a different scale that is almost twice the dyno jet chart. As your power seems to be right around 400rwhp at around 6500rpm. Another similarity, with both graphs shown, is the tq dip around 4300 rpm. Along with right around the same tq peak rpm then dropping.
May be right where it should be. Hope all goes well with it OP.
I know this discussion was 4 years ago but you are 100% right here. It's just the scales. The graphs look different because of it, but the numbers are almost identical. Both have 350tq at 3k. Reach max tq at around 4750. Hit 400whp a bit below 6k and hold it until 6500. They are almost the same. The only difference really is that the one hits max hp at 6100 and the other at 6200. Big whoop. These are also different dynos.
The different scales are what is throwing people off. I am familiar with this because I was a Math Major, worked as a Business Analyst looking at big data numbers all day long, and I've been an Engineer for the last ten years. People often use scales to try to deceive or show what they want. If you zoom way in on the graphs, they will look like huge peaks and valleys, kind of like the original graph. The farther you zoom in, the more it is enhanced.
Yup, for sure, but shouldn't affect the curve much, if any.
I am confident in where Darth is going, it also lines up with guys' advice like PatG when it comes to the importance of that merge. Go-to I think is still the Flowmaster if you can't do duals. https://www.summitracing.com/search/...d%3Aflowmaster

Worth doing anyway! Good luck and update us!
Remember, this is a 4 year old thread.
Different car, but this ls2 gto with the same cam and stock 243 heads peaked at 5800. So even lower, but the torque is massive. I think a UDP would have helped that gto.

Yessir, noted and agreed. Caveat on the GTO is that the exhaust is true dual so there isn't that Ymerge concern. Strikes me the OP had several minor issues stacked up costing some power. Not a ton and the overall curve looked ok, but noteworthy, ESPECIALLY if it was the same dyno. If different dynos then as usual take it to the track and use the trap speed to back into HP. That's your best sanity check a lot of times.
