Different Carb or EFI

What do think a EFI system would do for you? It might increase your gas mileage and drivability by a bit not really gonna increase your power output the 950hp and Nos is gonna be a quicker car and it would take a lot of years to pay back in fuel savings from the EFI system.

Im only 23, I have plenty of time to take in the benefits. IF I got EFI and Nitrous, will be better then 950 and nitrous, as long as it is direct port. Easier start ups, not fuel boil over, no tuning once done. I can learn to tune with a computer, rather then take apart the carb.
