My tune is set to peak at 27psi and it drops off to 24 by 6k and 21 by redline. All seems kosher.

Use the Cobb AP and flash it to Stage 1 AEM map for winter time and flash back to Stage 2 AEM for summer time. Stage 1 AEM should have lower boost?

I wanna see a video asap!!!

No way it's holding 27psi to redline, mine spikes 29psi at about 4200 but at 7k its closer to 17psi. You need a 30r or larger just about to hold anything above 25psi at redline from everything I've seen.
