Cm2250 derate

[Aleeex]

I’m usually pretty decent at figuring things out.. but I’m stumped. (Maybe I’ll find my missing mpg after this)


No codes

De mandated , rawze program


I started noticing boost limiting at 25-29 psi

Kinda thought maybe high elevations.. maybe the 100+ degree weather..


Datalog with insite while driving, “engine state - automotive governor” and when giving it full throttle “torque limiting” truck feels lazy


Within the last couple months , not in any particular order
Last week pm done with all new filters including fuel.
New imap
New exhaust gas pressure sensor
Fuel actuator
High pressure relief valve



I might be forgetting something… I did my air filter a few months ago… maybe that’s clogged?

What else can I check or pay attention to on the datalog to try and figure out why it’s de-rating
