Not exactly correct. Those numbers are a little high but "may" be obtained under the right conditions: vehicle, altitude, air quality, etc.
Mine at around sea level will hit about 19-20 w/GMTU on normal days. On some crappy air days, it may peak at 21.
(and yes mine is running correctly. No boost leaks and hitting full power by the RPD readings)
Like the tech from GM's performance division told me. In a nutshell, "It will put out the amount of boost needed to obtain the power levels required by the ECM and the torque management programming."

Well I guess you're right and everyone else is wrong.
Fwiw. The guy I talked to was named Bill. He told me my boost numbers were fine as long as I was making the hp/torque. I've been hitting that 19-20 since day 1 of the install. Learn down, I think not in my car since it's stayed the same.

Not even gonna go there. My SS is perfectly fine and runs well.

Plus donbrew, I'm at "sea level Alabama", so yes it would be different than anyone who's at any elevation.
Pissing contest? Not here. Just trying to keep some false info from being posted that EVERYONE should have 23 lbs of boost or more. Just isn't true.
