I checked the bypass valve set screw, took of the SC lid and the valve looks like it closes ok. The boost calculation in HPT shows MAP minus Barometric Pressure. The Barometric pressure shows 96 kPa which is about 14 PSI, I think that's right for South Florida sea level. It looks like my MAP is low at ~110 kPa which is about 16 psi.
I took a look at another ZL1 log and his kPa was in the 160's which makes sense and it was showing around 10 psi of boost. My MAF reading was also similar to the other ZL1.
Took the car to the dealer and they didn't want to help me or maybe couldn't help me.
Any suggestions?
