    Rebuilt Turbo, now VGT's stuck between 0-40%

    Hey everyone, 2007 Classic LBZ, rebuilt the turbo last fall and ever since rebuilding, my VGT's are not working properly. Took it to my buddy's shop who has a Tech 2, and the VGT's only show 0-40%, will not open any further. I did not have VGT issues prior to rebuild, turbo had some play in it...

    Question: Turbo spool

    I have a Banks 6 Gun on my 06 crew. At idle, it sounds like my turbo spools up for no reason. And as I drive down the hwy, holding a steady foot on the pedal, my boost goes from 3lbs to 7lbs. Back and forth. Not sure the issue.
