VGT % at idle?
Guys and Gals what should I be seeing for VGT% at idle? I got a P132b 2x's when towing. Plugged the laptop in tonight and 0 codes. Checked the VGT% and it was all over the place. Anywhere from 2%-85%.
What is normal?

I would expect between 25-40% as an avg. You shouldn't ever see as low as 15% or as high as 85%. This is the command %, not necessarily the actual.
That code is a faulty pre heater on an O2 sensor.
Sounds like you might have sticking unison turbo ring at first guess but not sure if the two are related?

Since you are running a tune, VGT% can be any value.
P132B is a code related to the calibration from the recall 06E17 (part of the Inferred EBP strategy). It means that there is a problem with the VGT system. P132B is a fault code that is set if the required boost levels are not achieved during a learn cycle or at specific speed fuel demand points. This code indicates that there are issues with the turbocharger, MAF sensor, MAP sensor/hose, IAT2 sensor, intake leaks, or exhaust leaks, etc. Frequently it is a sticking turbo issue. This code can also throw a P0401 EGR code.
The VGTCV (base part # 6F089) can be tested electrically, measure the resistance of the actuator coil using a DVOM, the resistance should be between 3.42 & 4.18 ohms @ 73°F EOT. If the engine is hot the resistance should be between 4.4 to 5.3 ohms @ 200°F EOT.

Scroll down to "Diagnostics", (but I am not sure how a tuner manipulates the values and commands):
...................VGTDC#.....EBP_G.........MGP
Idle.............60-82%.....0-6 psi.......0-1 psi
WOT............30-45%.....4-18 psi.....2-9
Ford book says low idle = 73%, high idle = 43%
RPM..........3300.......3000.......2800.......2600 .......2400
VGTDC#..32-42%...35-45%..36-46%..38-48%..40-50%
• EBP_DES should be 25-35 psi from 3300 to 2400 RPM under full load.
• EBP_G should be within 2 PSI of the EBP_DES.
• MGP should be 22-27 psi from 3300 to 2400 RPM under full load
