Default Re: Supercharging BMW E90 N46B20 320i 4cyl

I am new in the whole tunning field based on practice. I am reading a lot past several years but the theory is "fake" without an actual implementing in the practice.
So just generally speaking, do you think that I could do the job leaving the Engine management to the original ECU until I boost up and from this point upwards tune the proper AFR via MF2 and WaterInj?
Again, let's say my original map is 1Bar...if it is left in the OEM place, will it sens pressure above 1BAR? Will it inform the ECU that something is abnormal?
How should I trick the OEM Map to sens values like original until boost and after that just to feed the ECU with the maximum voltage related to 14.7psi absolute pressure(or theoretically speaking the biggest value that a NA engine with 100% VE could ever reach)?
Many questions...but that is the idea to share
