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.
