i was under the impression that a supercharger that comes with larger fuel injectors than what the stock vehicle comes with, a larger fuel pump, etc, needed a tune to adjust the spark and larger amount of air and fuel that the supercharger will demand under boost conditions?
I did not gain gas mileage with any of them I had (MP112 w/ 42lb, MP122HH w/ 60lb, and TVS1900 w/ 42lb). But I did not gain gas mileage either.
Weird, maybe it depends on the supercharger...
(sorry to threadjack, just an interesting topic that I have never heard of)
Might be larger injectors and fuel pump, but that's to counteract the higher pressure required to force the fuel into the valve.
