e-charger or mechanical supercharger will provide essentially the same "making up for some atms differences". Regardless of relative density @ various altitudes the delta gains will be similar, peak #'s with the FTS will be +~35% TQ and +~20% HP. Through some of the 'useable' rpm range over 50% is achieved.
Again, centri or positive displacement SC
do not compensate for altitude, unless provisions are made (Audi 3.0 SC) to recirculate some pressure.
