Exclamation 3.2l S/c ?

I need to pic someone's brain. I need to find out whats the diff between a 328 computer and an M3. Here's the situation, I have a 98 328i with an AA S/C. I swaped the motor for a 99 3.2L. Car runs good and seems to pull hard, the AA software in the 328 computer seams to work fine. No check eng, perfect idle. Dose any one know if I will see any gains by swiching to the M3 computer. Active wants about 400us for new software and 150us for a new mass air recalibrator. AA says Mass air and injectors are the same between 328 and M3. I have heard of people running 3.2L's on 328 computers to by pass antitheft so I just want to know if I need to swap Ecu's
