Buy the piggyback system that the kit originally came with

or

Buy a proper ECU to control your supercharger

or

Take the blower off and return the car to stock

or

Blow it up

I do not Believe that the JRSC Kit came with any type of FMU for the year 1990. I'll just go MS.

It should have something. Even the earlier Seebring kit had a rising rate fuel pressure regulator (Came with my kit and is in the instructions).

But yes, MS is the correct answer.
