32# boost & no CEL ?
E99CC LB Lariat, Auto -IDK issues or not? truck runs/starts fine, no drastic change in fuel mileage

Mods are.
4" turbo back ex. 6637 intake. PMT1 PCM, TS 6 with Tyrant tunes. Adrenaline hpop. d66 with van turbine turbine setup, (no WG) EBV actuator rod is in pedistal unpluuged, edge cts insight for gauges.


codes are- as expected
PO113 Intake Air Temperature Circuit High Input,
470 Exhaust Back Pressure Sensor Circuit Error,
475 Exhaust Pressure Control Valve Error
478 Exhaust Pressure Control Valve High Input
541 AIH (none on e99),
640 Manf Intake Air Heater Control Circuit

IAT*F = -40 on the scanner :wtf:

cts and snap on mt2500 scanner are seeing 17psi max boost while mechanical gauge i am seeing 32#. sensor skewing the #s to the pcm? fueling properly? ebv tube is clear as well as the sensor.
what am i missing? anyone else running a edge cts see the same?
14.7 atmosphere + 17# cts/scanner = 31.7psi.... lol

what ya all think or am in right field :doh:

Tuning can be set up to no longer display a CEL for overboost. No need for a boost fooler.

Cale knows how to do this, as do many others out there.

I can hit 40+ psi on my truck with no code. I don't run a boost fooler either.

I have thought of that, although tunes from cale on my truck needed a fooler. Throwing a new EBPS and tube at it today.43.5psi Key on , engine off, would indicate a biased sensor.

Oh if that's at KOEO then something is acting weird.
