Boost maxes out at 5 PSI, no apparent leaks.
Took the 951 out for a nice spin today and it seemed a lot smoother than usual, which was odd since there's usually a "rocket ship" effect at about 3,000 RPM, so I started watching the guages even more than usual and my mechanical boost guage never reads more than 5 PSI. I was seeing 14-15 PSI last week.
I do not have the CV installed and I've checked that the Relia-Boost isn't doing anything strange. From what I understand, this is exactly what would happen if the car had the stock CV and went into overboost, but that shouldn't be possible. All the hoses are good, I've checked the rubber and the hose clamps. Is it possible for the wastegate to get stuck open or something like that?

Either angels fixed my car or there was something that I didn't see at all in the relia-boost. Saw nothing weird when I took it apart to clean it but damned if everything doesn't work perfectly now. All 15 PSI now.

She's good now though!
Next step: Tires. RE750's seem to be scarce where I am...
