Truck run good although notice that it appears that it is not making any boost until about 2000 rpms. Not sure where to start. Any ideas or thoughts greatly appreciated. Fairly new to Duramax

Check for rub-through damage on the intercooler plumbing. A common issue.

Used starting fluid to check all connection points, no change in engine fpms. Took to shop and they found the problem. An apparent pinhole according to them. Either way it is repaired.
