if mass air is so great then why.........
Im getting closer and closer to building my 78 351EFI Twin Turbo Fairmont. I keep reading that mass air is the way to go. The car has an 86 5.0 mustang body harness, so it would be super easy to use a Mass air engine harness. But the real question is if Mass air is so great then why do most of the aftermarket EFI companies utilize a speed density setup? SDS, Speed-Pro, DFI, they're all based on a speed density setup. Each of them seem realtively easy to tune and work with, so what gives? THANKS
