Did you change any settings?

Double check user adjustments, make sure nothing was accidentally switched

I checked the user settings, especially the n20 TMAP setting, everything is normal.
Today I updated the firmware, tomorrow I will start and see what happens

I had the same issue after installing the JB4. What I found is that I am running the stock TMAP sensor, which, through reading the threads here, is a 2.5bar unit. The software is listed as a 1 for a 3.5bar, and a 2 for a 4bar. I reset the setting through the data cable to 0. That seems to have solved the problem. Boost has sorted itself out and no more CEL or "reduced power" warnings.

Not sure if that is the right fix, but it seems to work for me.

How has your car been with boost recently? Notice any problems? I think I had the same codes after my turbos have been installed. I put some chinese boost solenoids for a replacement at the same time. When we started the car it worked, I went out for a test and could only build 10psi boost. When stopped the car would throw a 2ABD error code, if cleared the car would start breaking up and eventually stall. And it showed up quite randomly. Tried OEM TMAP - same issue. Changed baxk to 3.5bar, then put old boost solenoids back in and that was it. No more errors after old boost solenoids were put back in their place. Also, I think this error you may sometimes find in shadow codes id tou shut down the car with JB4 connected to your phone. Just my 2 cents thougg, doesn't hurt to check, especially if you had done anything on that front recently.

The only thing that I observed was the boost at 630~700 RPM
Before was like 0.2~0.3 psi ,now 1 psi
But I think I solved the problem, I checked the tmap plugs and it was slightly unplugged from the adapt, and and it was dirty with filter oil
Now I get 0.0~0.1psi and no codes
