Oh. In that case, your boost isn't surprising for those wgdc values.

Update...I at a point where I'm going to start repeating things that I've done, because I'm at a loss and can't figure out what's wrong.
I've tried 3 different N75 valves.
I just replaced the valve cover/cam tensioner/cam seals.
Just re checked and re regapped plugs.
Today, charged the system up to 20psi for boost leak test and followed from y-pipe all the way to the TB with soapy water spray. Found a few small leaks...like brake booster hose/map sensor/TBB joint. I believe I took care of all those.
Tune is essentially Corrado's V3 file.
I will post two logs that I just took. The first is a two - three gear pull, and you will see that my boost is peaking slightly higher than I was able to get before. I would get around 17 psi max before, I can get around 19 now sometimes, but it quickly dwindles down. The boost always seems to peak higher in third gear...not sure why that is. You will also notice that something is happening around 6k or so where the WGDC goes to zero and I lose most of my boost. It will remain like this until I restart the engine.
The second log is just some city driving after the previous run, before restarting. Limp mode or something?
I really appreciate it guys! Please let me know if you can pinpoint what you think is the HW issue. I'll check anything you direct me to.

So, are you saying that's the max that k03's can produce? |

Yep. Depending on dp/exhaust setup, it isn't unreasonable.

You're chasing a non-issue. I'm actually surprised you're holding 16+ to redline. Post LDRXN from your file.

Yeah exactly as I thought then.
What are you trying to achieve running 1.5 bar boost on your K03's?
Besides from trying to blow up your turbos I am not sure what you are trying to do.
And running that much boost to redline you are for sure exceeding 100% injector duty cycle, and eventually going to melt your engine with the high EGT.
You have no problems with your car, but you are running far too much boost. Your timing is also like 2 degrees in the midrange.
Case closed then...

Okay, I was under the impression that people were successfully running this tune with K03s. Thanks for clearing that up. I suppose I'll have to tune it down until I get some K04s. Curious though, was it limp mode that was causing the car to not boost after a run...and was it constant negative deviation that caused it to do that?
Also, if someone could just let me know basically what I would have to alter to lower max requested boost in this file, I would appreciate it. I'm on the wiki right now trying to figure it out.

Can I just alter KFMIRL and/or LDRXN to slightly lower maximum requested boost?

Well, I gave that a whirl. Could someone check this out and see if it would accomplish about 17 psi max?
And let me know if there's anything else I would have to change?
Thanks

Get a wideband and make sure your fueling is sufficient.

Because you're out of fuel with those boost levels. Do you want to melt things? I think not.
