iv got a msd blaster 2 on right now.its running with a 4 prong ballast resistor..what ohm resistor is the 4 and should this resistor be run with the blaster 2 or should i change to the double prong resistor..tanks to all ..j

The 4 terminal resistor is .5 ohm on the coil side, the ECU side is different (5 ohms). Make SURE the resistor is hooked up right. If you have a later model ECU, you MAY have a 4 pin ECU and don't really need the 4 terminal resistor

What does MSD recommend for your coil?
