Guess my total HP!

Here you go, this is with both pumps installed and the same result with just the intank pump installed and the inline bypassed.

I bet there is a restriction in the fuel system somewhere. Run -8 line to the fuel rails and remove that chance. In the video the fuel mixture stays good even though the pressure falls off. Can you load the dyno and roll up to speed rather than matting it?

It's not the fuel rails and cross over, that's 1/2", so we're good there.
I'm gonna install an inline a1000 and -8 to the fuel rails, I just might Y it off before the rails also and feed each one, then of course back to the regulator.
That was loaded Red. Ya, the a/f ratio is only staying good because I'm dumping a butt load of fuel as soon as boost comes on. Commanded is about 5:1 a/f ratio lol, but it can only maintain 11.0 or so for a second, then go lean.
I normally load the dyno 10% for all NA trucks. That makes the dyno run about 3-4secs, depending on how high I take it up.
On a light turbo setup, I load it 20-25%, enough to spool the turbo.
What you're seeing here is 30% load, but in second gear, so it's loaded like a mofo.
Just to compare this, a 300whp NA truck would probably take about 15 secs to complete it's run on a 30%, that is if it can even pull 30% load.
It's like trying to tow a 8000lb trailor, lol.
The dyno can load the truck so much, it'll stop the wheels, overheat the trans, or break the trans, ha!

I'll get the stuff ordered James.
