and actually noticed a increase in power, Well power sooner, as to be expected considering the voltage steps up sooner in two steps instead of the more regulated three. But i ask the same question before hand and what i gathered was it would be safe. My guess for the reason for a three stage TT controller is to more closely keep the fuel ratio at a optimum ratio, and maybe better power with the lower setting, But i was running a little lean before and after i noticed a slight increase in low and mid range power. Yeah thats a little long but i figured that maybe you could let me know if you get the same result with the power difference.
