Check your alternator. Could be when you enter a good amount of boost the alternator isn't doing its job. Could be a pulley making it do that, I'm not sure of your setup tho.

Yea check the belt, slippage could be the problem. It seems like when you enter boost since you're running that much boost, it sounds like your belt is slipping on the alternator pulley because whenever the alternator drops below a certain amount of output, it will trigger the battery light.
Check the battery, if the battery is holding a charge at the normal level, then its most likely the alternator pulley slipping on the belt.
