AIR Reduction Volts - lower for underdrive pulley?
i have march power and amp series underdrive pulley set. I have calculated that it turns all accessories 30% slower, except the alternator which is only 2% slower. so im not sure how the smog pump works exactly, so im guessing that since its turning 30% slower, should i reduce the "AIR Rich/Lean Reduction Volts" from 101.77 to 71.24? to help retain stock o2 readings. thanks. using TunerPro RT on $8D
