MAF question

Can someone tell me what the maximum boost pressure should be? I am seeing 36 PSI at 100% load booting it up a short incline. Does that sound about right? I just had all 6 of the glow plugs replaced and had the turbo o ring, the boot at the turbo baffle and the baffle o ring replaced at the same time. Boost pressure has risen since then.

Thanks to the brain trust for this great forum!!

My engine will only boost to 21psi measured at the obd2 port.
BUT you seem to be measuring BOOST (BST) and RedPillar is measuring Manifold Absolute Pressure (MAP).

The difference is Ambient Pressure which is circa 15 psi so add that 15 psi to your 21 psi gives... (drumroll please)...

36 psi.

QED.
