440 going with efi?

I went with msd on my Charger, because it only has one pigtail on the back. I want the car to look stock. I have an aftermarket fuel tank built for fuel injection that looks stock. The pump is in the tank like it should be. The regulator is back by the tank so only one line had to be ran along the to the throttle body. There is a tuner in the glove box if I want to mess with it, but I'll let it tune itself. I hope to fire it up next week when the exhaust gets here.
