Hey guys, new here. Been lurking for a while now as the forum is extremely helpful. I'll cut to the chase.

Recently went FBO.

I did the intake, CP, FMIC and a JB4 first. No issues with install or performance, mainly used map 1.

Got to the DP this week. Played with map 2 and map 5, map 5 was the best. I could feel the increase in low end power. I was driving pushing pretty hard, and I heard something release pressure rapidly, then I went to drivetrain malfunction underboost. Found out that the CP bung plug came out partially- fixed it and the car was great again. The car was running great as recently as last night. This morning I went for a drive and the boost was acting funny. Lacking low end power, but the engine would rev as normally and eventually I would get significant boost if I throttled hard enough, but it was still lacking.

Been trying to figure it out all day.... wondering if I have a boost leak.

I took a JB4 log (map 5) in 3rd gear WOT from ~2000rpm to 5700rpm. Could someone please help me interpret the attached log?

Sorry if I'm in the wrong spot for this.
