Hello.
I was driving home from work on the highway accelerating up a small incline when I lost power. I was close to home so I limped my truck there. I am showing -2 boost at Idle and it goes to -4 at 2500 rpm. There are no codes showing. I have the Sct live wire hooked up. Took off air intake to inspect turbo and i didn't find any excess play. Put a power probe on the vgt and it was reading 4 ohms.

If you look at the MAP hose, make sure its connected and not cracked.

It's common for the Turbo to seize and produce low boost, but negative boost not sure. Monitor VGT and if it approaches 15% or 85% it points to opening the turbo and cleaning it.

Also, to make sure the sensors are operating correctly, look at MAP, Baro, and EBP at KOEO and should be about the same, around 14.7, less if you're higher in altitude.
