Efan issue
I installed an Efan when I got my procharger installed and now when I hit half throttle my headlights cut out until I let off the gas. Does this for the first 10mins of driving time. I'm running Xenon 12,000K HIDs. Efan is a Black Magic

I doubt it the Efan has anything to do with it, I bet it's the 12K HID.

Stock standard 110 amp alternator?
May want to swap in a heavy duty 220 amp alternator. They don't put out a constant 220 amps; they increase amp output at certain rpm range, which sounds like what you need with the load required with the e-fan and headlight mods you added.
