Ford's values for VGT%

Engine hot:

KOEO=0
Low Idle=73
High idle=43 High idle for this is 2500 rpm
Operating Range=0-100 %

I did a "poll" on this topic on another forum. Interesting discussion on VGT%

http://www.ford-trucks.com/forums/11...-hot-idle.html

I didn't go low enough for a lot of voters, as I found out. Mine was pegging 85%. Even with a new turbo. Now, with some time on the new turbo, my VGT% is running about 76%.

Never could get it figured out as to what causes the 85%, or what to change.

high idle when engine cold mine will hit 85% for a little bit and then calm down back to the 70-75%.

normal driving is between 40-60%
