Im running that combination now at ~11 psi not 9psi. No knock. Dont plan on a dragster and that isnt what this is about. Just wanting to know why I didnt get the results that most ppl have posted for the mods I added? Stock run was a 16.9. "1st Run" Radix, e-fans and 55hp wet shot @ 14.2. "2nd Run" New Mods hoping for a 12.9 is that impossible?

I would take it to the track and see what it runs. Try not to get caught up in the dyno numbers. When I modded the 5.3, I got stuck in the dyno numbers and I was frsutrated. I started going to the track and got the 5.3 into the 13.40's on the 22's. With the 6.0 @ 448/457, I went 12.5 with slicks, and 13.2 with 22's.
The intake temps @ 11# seem very low. You must have a large heat exchanger set up. Seems that the power past 4500rpm is really falling off. I put the 3.0 pulley on my 5.3 and the intake temps went through the roof. I made a ton of torque down low, but when I went WOT on the dyno, it was detonating and couldnt get a full run on the dyno. Intake temps reached high 100's.low 200's w/ timing around 10-12 degreees. I switched from a 3.0 to a 3.25 pulley and ran 16 degrees of timing and made 406rwhp.
I had better luck with more timing and less boost. Do you give an idea, here is how things progressed for me with my 6.0.
448/457 - GT2-3, TOG mid legths, true duals, 3.1 pulley at 5#
473/503 - same mods as above plus alky kit and 2.9 pulley and tune
503/526
More tuning got me to 512/535. All runs above were made on the same dyno. I made 545/565 on Rick's Dynopack without the 22's. I am not sure if the 22's would cost me 30rwhp, but that is the only difference I could think of.
