Fuel Injection on a 383

The Fast EFI would need 2 throttle body's on my application. I have already checked into it and with a Twin Turbo set up it only gets more complicated. Plus the set up with everything is around 4k to do it. The MS2 I believe is a way better set up and has a better price point for BOOSTED Applications in my opinion. I am about to find out for myself.
