OK, fuel management is needed.

But, it is cheap and easy. It is mechanical versus computer.

I noticed that the AF readings were just slightly low. No detonation or anything but the digital read kept slipping a little versus reading constant while on boost.

I decided to wire in the fuel solenoid from my nitrous solenoid with a small fuel jet. It was wired directly to the supercharger so it would only turn on when the supercharger was on at WOT.

Perfect, .7-.8 readings on the AF digital reader. And a bit more power or so says the butt dyno.

So basically if the supercharger kit makes it to sales (everyone cross their fingers) it will include a fuel solenoid and an injector that is welded into the intake. Basically just a fifth injector.

As soon as my new 7 to 8" pulley is turned, for maximum boost, I will have to take it out to the dyno and really tune it with the fuel jets.
