That is accurate.
It's not a matter of "correcting" the vehicle, rather, correcting what the ECM is reading.
If you haven't adjusted for the signals the 3bar MapV is sending/receiving to the ECM (and other sensors in / along it's arterial path) via means of tuning, and you just install the 3bar, without tuning for it accordingly, you will experience the results you've previously reported.
