    Log ambient pressure and remove it from your calculations.

    You can use the same PID just note the pressure, ignition on but engine not running.

    average ambient pressure is 14.7psi so you take 29.28 - 14.7 = 14.5 pounds of boost.

    Okay guys yeah, @ 4100 rpm, 202% absolute load 14.18 ambient psi and 34.942 charge psi...I'm at 20.76 psi of boost.

    This makes sense now haha.

    This is apr stage 2 with 73.4% ethanol content, passive auto zf8.

    Thanks

    You can expect 1-2psi more on pump, or cooler weather, barring and potential leaks or weak wastegate.
