GM control module

If I use a GM HEI ignition module, can I remove my ballast resistor?
Yes you can as long as you either
1. Use an HEI E-core coil with low resistance or
2. Use a canister coil with 1.0 to 1.5 ohms resistance. This resistance is required for the coil, not the ignition module.
You must retain the ballast resistor if you wish to
3. Use the stock Chrysler coil with .5 ohms resistance. The ballast resistor here will prevent the stock coil from overheating.
The HEI ignition module enables you to use less primary resistance, but will function fine if you wish to use more resistance.
