I'm running a powermaster squareback. I've never had a mopar charge like this. The car was always burning up voltage regulators before. I always blamed the cheap vr. I'm not running a ton of stuff but I have upgraded headlights, ez efi, the in tank pump, stereo, and dash full of auto meter gauges. Before the blinkers would slow down, headlights would dim. All that stuff, now it's nice and stable. I wasn't sure if it was going to be money well spent with it being hard to find good vr, but it seems to be working good.
