Yeah, running those logs may pin point the problem since the system is pretty much all controlled electronically.
Let me know if it would be helpful to compare stock values. Does your JB4 pull values sent to the turbo solenoids and diverter valves?
Isn't max stock boost 16-17psi?
When the hpa value (119.75) is converted to psi, I get 17.4psi
