M90s come on several different vehicles and there are many different generation M90s as well. Is there a particular one I should be looking for that would be best? Can the M112/MP112 be run at low boost as well without having to make modifications to the ECU? I was looking to keep the stock ECU and not have to go through tuning, at least right now. It would be nice to have that room to "Grow" without having to change superchargers and I know that the M90 gets really hot at higher boost and rpm levels, but IIRC from previous research a while back that the M90 has less parasitic loss, thus making is a more efficient low power blower.
