Should VGT Commanded and Actual match?

shiftin04 · Dec 9, 2025

I recently swapped the failing turbo in my 2015 F250 for a Cheetah Fleece. It had the P132B at first so I performed the drive cycle reset I found online. The code hasn't come back since and the exhaust brake works again. But while logging I've noticed the commanded and actual never match. An example would be the commanded is reading 80% and the actual is 39%. I read on another forum that the commanded is actually the duty cycle being commanded by the ECU for the solenoid so it'll never match the actual. I have access to a Snap-On scanner that can run the relearn, but figured I'd ask before going through all that.

I'm using HP Tuners VCM Scanner to watch everything

The actual lid is assumed. These have no way of knowing where the vgt actually is. Commanded will be whatever the tune is calling for. Hp tuners has got a bunch of different lids I’ve found for different vehicles that will read, but not read right.
