Voltage issues after turbo install
example 1: cruising down the road, 50mph, 2000rpm, barely touching the throttle. headlights, dash lights dim, voltage gauge drops to 11ish. Let off the gas and it comes back to normal 14+
example 2: fired the truck up after it sat for 12hrs. headlights and dash lights were dim. tapped the gas a few times and they came back to normal. voltage again went from 11-14ish.
What could be causing this? The battery and alternator are newish. (2months old)
