explorer express supercharger 4.0

Has anyone used one of these before? And are serious tranny upgrades needed if I use one. I have the 4.0 SOHC.

I dont have one. A guy who was here named hotwheels (spelled oddly though) had one and loved it. I talked to the guy at EE and he was extremely helpful about it and even sent me a full set of instructions. They are completely bolt on, down to the zip ties.

They come with a new fuel pump, new injectors and the flasher. Doug at Bamma Chips does the programming for the flasher for them. I just don't have a way to get that kind of money, or I would have one already.
