15% vanes all the way open (wide open throttle, bigger turbo) = largest cross-sectional area

85% vanes closed all the way (high idle mode, smaller turbo) = smallest cross-sectional area

85% means the vanes are open. The lower the percentage means the vanes are closed or closing. It would probably be easier to figure it out if your truck has the vane sweep strategy. I don't monitor vgt % so I don't know what it does during regular driving.

on edit: got it backwards i guess lol

normal driving for me ranges between 40-60%

If you lug it up a hill and sharply let off the VGT will go to 15% to relieve all pressure
