I have no dyno nearby but today I checked the boost PSI at RPM in 4th from 2500 to 7000. 3 PSI at 2500, 5 PSI at 4000, 8 PSI at 6500. Stage is so limited by the intake.

I also have external WB O2 for real reading and full datalogging along with the data from the engine ECU

Did you build the Knock sensor listed at uprev??
