To clear up a few things, this method does work if you know what your doing and why... 99% of people wont need this. Yes the proper way is to have enough MAF resolution for you particular setup... It is not recommended if you don't know what to look for or why its even used.

The MAF calibration ...

you can also understate things if it's an emergency and boost will go up... you will have to remap a few things if you try this approach...

options are to reduce your fuel demand if the pressure deviation concerns you. Here are a few below...
a. lean mixture
b. lower airC limit
c. reduce ethanol content

I also suggest maybe playing around with the target pressure. You may find for your setup you might not ...

___________car is going in and out of closed loop under WOT

- try toggling "Use AFM to determine WOT" Its under --->Calibration--->Closed loop
- log your AFM.c and notate where it is under WOT, then set the table data 50-100 less than what you logged. This will force open loop under WOT.

Auto tune is for MAP based fuel tuning only. Your vehicle(1.5T) uses the AFM only

You dont need to check that box. The ecu will take care of the afr targets quite welll based on load. This also helps with fuel economy. You can check it however; just tune to your liking so your fuel economy wont suffer too much...
