From the Alpha Strike Companion:
Pg 94: MASC and Superchargers (conversion from Battletech)
I think this should clarify if Myomer Boosters for Protomechs should be counted as MASC/Superchargers? Currently they are not explicitly mentioned there but I can't see a reason why they shouldn't count since they have a similar effect to MASC? This could significantly affect PV calculations either way later on.
