I'm curious about this. The numbers are too close to my junk truck without an SXE

I'm pretty sure the most people are making right now with stock fueling is in the ~535hp range (backed up by track times).

Details? I'm curious. I feel my truck makes more than what it showed. It runs extremely well... 11.82 is on a terrible 60ft and I don't lock up in second. Maybe I should dyno it somewhere else?

Using the 114mph the calculator here says 537hp, pretty close to your best dyno run.

Dynoed Sxe369 Yesterday!
Were you able to make changes in the dyno try running with. Several different timing values. Record results. Then run what runs best. Repeat with timing. Fuel delivery and injectors

This is a long video of a dyno session we did with a customer and his 06' 5.9 Mega Cab with 100% stock truck other than 369sxe w/.80ar wastegated T3 housing, Hardway tuning, and a PDD 850HP 48re transmission.
The short version, it did 537HP on it's best run. That's uncorrected raw HP, with the typical altitude correction the weather station calls for in Feburary when these runs were made, about 16%, it would be about 620 HP. We know correction factors are too high for boosted applications, but somewhere between 5% and 10% correction is what most trucks actually put down at the track vs. our uncorrected numbers.
Skip to 8:30 in the video for the first dyno pull.

It looks like the dyno jet numbers were pretty close to your track numbers, despite the 7% correction factor (SAE 1.07).
On pretty much every stock headed 12v cummins we've ran, the earlier we can make it come up to full boost, the better the power numbers. I'll bet if you would have ridden the brakes for a bit at 2000 RPM, built about 30 psi against the brakes, then released brakes and floored it around 2200 rpm, you would have made peak power closer to 3k RPM and probably picked up 25 to 30 more HP.
With the track average calculating to 537 HP, your peak power is probably close to 550 HP and your average power through the RPM window you run at the track ends up right at that 537 calculated number.
This is good news! It means it's got a ton more left in it with that turbo combination. First step is to lock the converter in 2nd gear so you have consistent back to back testing parameters. Then while at the track, make tuning changes and see if MPH improves, even if you get a bad launch that spins, MPH is generally consistent and a good indicator of power put to the track.
The first thing I'd try on your truck is more timing, bump it up 2 to 4 degrees and see if it picks up MPH!

Interesting, thanks for that good info! I wish I would have known that. I talked myself into to it and will be removing the 12 valve and putting a 6.7 in my truck and I will retain the sxe369, will also modify trans while out for second gear lockup

I know, honestly the 12 valve was a good idea and I'm glad I got to play with one for over a year, but I think it's time to get back to the electronic motors that I'm used to and prefer. May tweak the pump and timing a little bit more and go to the strip one more time on it and see what happens

I would have thought that combo would be for 600-650 plus

I thought the same, some 5x18s should be here this week, going to give it a second chance. If it will go 11.50 something next time I go to the track, I won't swap it to a 6.7.

Somthing just isnt right with it. Keep working on it. I have seen 600hp with 5x14s and a 64

I had mine on our dyno a week ago. Did 598hp 1256tq with a 1.006 correction factor lol. Truck spun on the rollers but I'll get another day to mess around with it some more. I'd say final numbers on mine would be 620-630HP. My setup is a 369 with the .80 gated t3 housing, 6x.013's and an edge with the hot unlock. 58lbs of boost. I would think you have as much fuel as I have.

Swapped 5x18s in went to the track saturday and got down to 11.71 at 116 and on my go pro in cab I can tell its wound out to almost 3500 before the 1/4 mile line so now I'm gear bound on my 28in tall slicks, either going to have to get a 33 inch tall tire or drop to a 3.21 gear in the rear.
