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.

Ok. Thanks. I’ll give it a try
