Do the same on distributor boost nipple. Give it some pressure ie. 1bar and rev to 4000.

I would try a WOT pull in 4th gear from about 2000 RPM cruise to really see where your boost threshold and peak boost occur. With a 915, I get a lot of apparent lag in 2nd and 3rd gear but 4th appears to have reasonable numbers with peak boost at 3200 RPM or so.

Here's what appears to be a stock 930:

Seems like you are not too far off considering you are 3.0l vs 3.3l

Checking the AFRs again and i was at 11.5 at idle, when I pulled off the air box (K&N) AFRs jumped to 12.8.
Could the air box be part of the issue?
I took it for a ride w/o air box and logged some more data. No difference in onset of boost.

How do I post an LM2 file, I will attempt.
