Well, were trying to do a process of elimination. If you go MBC only and it works fine, you can rule
out your turbos being bad or the line running to and from the turbos.
More then likely it is not a software problem, since many other people are running it without these problems.

try mbc only......
i had a customer who did the stage 3- software and had a similar boost issue. The mbc only cured the spool up. Not saying that it should have to be done with the stage 3- software, but it did fix the problem for him.

This is BS! I have the same problem but with stg 1 AMS software
I already tried a new N75.. did nothing, no boost leaks, cleaned and lubed DV's, made sure they were tight... I can't find out what is causing this either.
The fact that my car does the same thing with K03s and different software would lead me to believe that it isn't your ECU causing it.
I have stg 2+ - AMS chip, labree split dps, very open exhaust with no cats, forge dv's.
With k03s I have seen mine spike as high as 23 (this is at low rpms in 4th or 5th) , so it spikes real high, goes into limp mode, and usually resets istelf when I shift. Does this all sound familiar?
This is pissing me off! Its going to make my k03s blow up (which is good...) but on the other hand I want to fix the problem before I get new turbos.

Afterthought, This spiking up to high boost then dropping way too low is exactly what my Allroad is doing...
I'm getting 4psi most of the time.
You say you are going into Limp mode...How can I tell I'm in Limp mode? and how do I get out of it?
Still on original N75, so that could be the problem, but I don't want to throw parts at it if I'm not sure...
