REV-N-NATOR vs MSD Street Fire CDI

I run the fbo box in my duster and works flawless. Bypassing the resistor just allows full battery/alt charge voltage for a bit more power I would think. They included a jumper wire that left the resistor in the car still. I keep the stock box and coil in the car just in case a failure I can swap stock parts back in to get home. Nice there was no cutting with the fbo kit. easy to reverse if need be.
