req boost is well below the MAP limit, which is why he's seeing throttle cut IIRC.

so he really needs to INCREASE ldrxn and cut a ton of WGDC
so I have increase ldrxn to 255 and set wgdc to 75% on both maps and requested boost never meets actual. What am I doing wrong?

Impossible to say w/o looking at the logs, but until you learn more about PIDs it will be very hard to spoon feed this side of tuning.

Barely any boost until 3.2k on a K04 sucks.   Why is engine load so low?  Duty is flat out so either leaks/dead turbo.

ps_w is so very low. MAF readings and msdk_w are all over the place. Throttle cut after ~5200 RPM.
Lower the DIMX even more in 3500+ RPM zone.
Is your MAF properly scaled? If it is - double-check DV.

Absolutely the last thing you should do. I have zero idea why you think this is at all the case.

ps_w is crazy low, so either your MAF is horribly underscaled or you have a gigantic post maf pre turbo inlet leak.

Spool is incredibly lazy for a K04. Even if we disregard that:

Your LDRXN is still too low, and DIMX is still way too high, or Q2 is way too low, or both.

The whole log is an utter mess, from start to finish.

It isn't clear at all you understand anything from the tuning page, let alone the FR, especially if you think (for some bizarre reason) KFMIRL and IOP have anything to do with the problems you're seeing.

Best way is to use an MBC to not kill turbo/rods with big overboost. Then u can set a desired boost wich will be limited by mbc..

LOL best way is to double and triple and quadruple-check that the car is mechanically sound, and that there are no leaks. But yeah, most people will just say "yeah I've tightened up all the clamps, it's air tight" so what can you expect?

I have no logs because I have a boost gauge (makes things easier)

Unless you are intentionally underscaling the MAF, yes, something is wrong.
