Boost pressure

[Rawze]

(06-25-2025 )Ravenwood Wrote:  Cm2350 600, reviewed file, demandated, put a new head and 6 injectors, then installed the revised file in. This thing performs better than ever, gained about 20 gallons of fuel in the tank a day.
I noticed on the few longer grades my boost will peak around 39-40 psi. Every time it does I get the (intake manifold pressure voltage below normal code).Engine performance doesn’t seem to change at all just an annoying check engine/service advised. Checked the sensor on insite and it steady at 87.5
Any help would greatly be appreciated

That is too high for a CM2350., It should crest at about 34~ish psi max.

Get with whoever made the program and have them turn down the boost levels.
