I wouldn't really call it plug and play. You need a good electric pump in line or in the tank, switch all hoses over to fuel injection hose. Then you can install the efi. Which isn't too bad. The throttle /kd interface on the Sniper needs a few parts not included to make it work right.
But it runs great. I had to swap in a higher flow pump to keep up at wot but it starts instantly and runs great. I'm still playing with it.
