Low boost, higher egt's

[simon999]

I installed another actuator , tested turbo travel range with plastic gauge was together with actuator. Im still getting same 20psi boost max and high egt`s. Today I monitored insite and 'exhaust gas pressure' shows 30inHg (0.88v)while engine is Off. Is it suppose to be like this??? What pressure suppose to be while idling or driving?
Now when engine is at idle it shows about 32-33inhg at 650rpm , 35inhg at 1000rpm, 39inhg at 1400rpm. I tried with another older exhaust backpressure sensor but its same thing.Also when driving if push pedal and boost goes more than 10psi insite shows 'engine torque mode' changes from 'accelerator' to 'torque limit' mode.
