Fully functioning stand alone Nag1 controller

You need the controller, a map sensor (can piggy back off stock), tps sensor (piggy back off stock), speed sensor (included in kit), magnetic pickup (included in kit) and a nag1 transmission and converter.

I find them all the time for $750 and generally speaking if they are in good working order and have a good cooler they will consistently hold 500++ wheel torque and horsepower. So you can probably make the whole thing happen for $2000.
