I think i got somewhere!
I tried 4 different n75 valves, and this one gives me full boost and no limpmode (yet).
STILL a large deviation from requested to actual, but it's much better now.
Thoughts on this log?

not sure why you're doing this.
why not just disconnect the wg line? It's equivalent to 95% DC
just be careful, dont overboost, hopefully you have a gauge

LOL that requested boost is hilarious.
You're wasting your time.
Find a real tuner or start from scratch.

Also the n75 is a safety measure. I want to try and finish off the tuning of this file myself.
But as a noob, i need the n75 there if i fuck things up.
Also. With no n75, does the ecm treat fueling and timing the same as though it atill had control over boost?
I noticed that i get no limp mode, or codes for under/overboost, when i run only the wastegate.
This is even though requested and actual vary by as much as 6psi

Lol man, curiosity got the better of me and looked at that log.
Boost request is a joke, locked wgdc , lambda leaned out on high rpm. This file is a joke. Do these "tuners" even look at compressor maps, turbo limits etc, like go run with cwmdapp 95% dc and see what it does if you gonna target boost req like that rofl.

Sheeit.
Guy is a reputable tuner also.
But, and to be fair to him, he was trying to tune this with feedback from a shotty n75.
What happened was that I had an n75 from a 2002 in my 2001 car. It just so happens that there is some weird bug with those.
The n75 will be plugged in, and not throw any codes, nor will it cause limp mode, but it will basically run as though you had the wastegate hose unplugged.
On top of that, my turbo is super old (210k miles) so with no n75 control and just wastegate, the boost profile looks somewhat normal.
it spikes 22psi at 4k, then tapes down to 15psi at redline.
I'm assuming the high duty cycle was an attempt to lift that low 15psi redline.
we were trying to get 20psi peak, and 18psi hold.

That doesn't excuse the rest of the random weirdness in that file.

Jesus i'm reading the reset of your post now more carefully, and just about every sentence is ... not right.
18 hold on k03s? with stock wg and fueling? Really?
