What can a constant - number on fine knock learn mean

I would log what you had, but also add either boost target or boost error. I don't know which one the AP would have, but it should have one of the two. That said, based on the short term trims I saw in your last log your car isn't trying to make any crazy fueling adjustments. Log it on your drive home anyways to see what it's learned for long term trims since the reset, anyways. I would also highly suggest not doing any pulls until you get this figured out - maybe one more to log boost error if you want to risk it.

I'll try it just once, worst case I pop my engine and get a warrantied new one right lol

What intercooler are you running? If stock, is it modified? Check the seams to be sure no fingers coming unfolded. Especially near turbo outlet corner. My intercooler started to open once over ~17psi on stg 2. I caught it early and bulletproofed it with home made kit and jb weld. It’s been holding up to above 20psi now.

Oh damn I didnt even consider that. It is the stock intercooler with 127k miles and it's been running 18 psi for probably about a year

okay grabbed a datalog on the way home. i noticed a few hesitations probably a quarter the way there but had no open roads stuck in traffic so towards the end i was actually able to build some boost
