Drag strip log + boost dropping after 5500 rpm

[threetirtyfive]

Hi guys
Today I did 7 quarter mile runs in the wet but getting a best time of 13.49 @ 103

On a couple of runs I got a half engine light and 30FF, the underside of the charge pipe is soaked in oil, however my boost gauge shows that it's still making good vacuum -19psi, and appears to make full boost (for my car 12.5-13psi).
I decided to log with MHD the next drag strip run and noticed the boost dropping above around 5500rpm.
Can you guys take a look- is this likely a leak on the charge side? I notice the requested PSI also actually drops...

(EDIT: yes car is in open loop, I'm aware of that, more interested in the boost drop off )

If you spot anything else odd about the log let me know.

Not sure if max IAT of 136f /57c is acceptable or needs a bigger intercooler? I thought it would get higher than that.

you should take a look at base/adder and load tables

30ff and missing boost target by 50% usually means a boost leak. Vacuum lines, vacuum canisters, charge pipe, etc. You should probably look into a better FMIC as well. Your IATs climb pretty quick and you're only in 3rd.

Something is up with your bank 1 o2 sensor as well... it's reading flat 0 fuel trims and 15 afr the whole way through the pull.
