Default Engine bogging down with any swift throttle change
I also put this in my build thread, but that thing has gotten so long and often times mundane that I doubt a lot of people are reading it.

Long story short, engine is up and running but...

But, it still has the same bad bogging and event stalling if the throttle goes up with much of any quickness. Even bumping the RPMS from idle to 2k will cause it to bog and stall. It was doing this before rebuild and I thought I had found the cause in that my charge pipe to cold side coupler was splitting as I was dismantling things for teardown. I thought it had a small tear and my problem was a vacuum and pressure leak. That is not the case.

I'm still bleeding the coolant so I haven't had much time to diagnose anything. What I did notice is that the engine idles better and has less of a problem when vacuum hose that feeds my OEM boost sensor as well as my boost gauge is off the UIM. I use the nipple below the BAC with a tee to feed both OEM boost sensor as well as my aftermarket boost gauge.

When time permits I'll start testing TPS, OEM boost sensor, AFM, etc. Any thoughts on this would be appreciated.
