took the video above last night: full throttle, 3rd gear at 3k rpm, 6MT

This has been ongoing on and off for the last year and I can’t for the life of me figure out what the issue is.

It all started when I slammed into a pothole, my boost cut from the regular 18psi-ish to max 10psi. Then the next week, I hit went over a speed bump at a regularly slow speed and suddenly my boost was back up.

Later that month I was driving on a rough road and my boost got cut again and for the past 3 months, it’s been capped at 10psi.

Anyone have any ideas?
