Default Boost Leak? Logs included - 05-15-2021, 01:25 PM

2020 C43 with Petro 94. Installed the JB4 with BCM module. Ran 0-60 and 1/4mi times with the onboard computer both stock and running map 1 and 2. No decrease in time and butt dyno confirms. Car is runs 0-60 in over 5 seconds.

The turbo noise (woosh noise) increases with maps but it seems like its falling flat. The logs seem to show boost tapering off to almost stock by the upper RPM. Thoughts?

Log of map 1 and 2 attached.
