Exhaust/Boost Leak?

[Sethmiller]

Hello guys and gals, fixed my p0107 code on my 2010 LMM Duramax. Still getting a weird surge sound that is higher in pitch than usual. Thinking it’s an exhaust leak or boost leak somehow? I’ve recently installed new up pipes and manifolds, sdp y bridge kit, hot side pipe, and the sdp intake. Any ideas on what is making this sound? Will post link with a video

Sounds like it could be a boost leak.
If this is the only code check the following:
Possible Causes:
• * Intake manifold vacuum leaks
• * A loose or improperly installed MAP sensor
• * A restriction in the vacuum source of the MAP sensor
• * MAP sensor low reference circuit for an open/high resistance
• * MAP sensor 5-volt reference circuit for a short to ground or an open/high
resistance
• * MAP sensor 5-volt reference circuit for a short to voltage
• * MAP sensor signal circuit for a short to voltage
• * MAP sensor signal circuit for a short to ground or an open/high resistance
• * MAP sensor has failed
• * ECM has failed

I’d say turn on your blower with vent set to outside air, not recirc, and drive it. If you don’t get exhaust smell into the cab then it’s probably not an exhaust leak

I’m thinking maybe the up pipes are loose or manifolds?

Sounds like a boost leak. Sounds like a similar issue I had at one point. Mine was the factory intake horn/y-bridge. It was all jacked up. I'd check up pipe bellows and for sure do a boost leak test on it. I know there are some write ups or youtube videos on how to make one and/or where to purchase one.
