Where should it be at at idle

Depends on how it was demandated. An MM'd truck, the turbo is usually only set just high enough for it to make slight positive pressure at the intake if someone has taken the time to set the idle region on it. You can look at tis position and see what it is with insite, and also you can remove the IMAP sensor from its mounting hole at the intake and see if there is a slight positive pressure coming from the mounting hole.

Well. You may or may not believe this but in talking with Unilevers , he had suggested a few things. The last being pull a piece of the exhaust off close to the turbo. In doing that the truck ran normal. Further investigation I discovered that the remaining 1 inch of material I left on the outer edge of the DOC/DPF broke off and plugged the screen in the DEF decomp tube. I never would’ve thought. Anyways it’s all good. Thanks to all who had advised me in this matter. I guess the best idea is to remove all of that material. Happy trucking
