You shouldn't need to adjust any sensors if your car uses a MAP sensor, that's all myth. The O2 sensor will make sure the amount of air vs fuel is "correct" (stoichiometric), because it looks for any unburnt oxygen in the exhaust and adjusts fuel up or down so that there's zero (but no extra fuel either). Doesn't matter if you're adding nitrous oxide, hydrogen, propane, natural gas or whatever else to the intake or combustion chamber, the O2 sensor will take care of it, and the ECU will add or subtract fuel so that combustion is correct. It should always show up as 14.7:1.
