For those of you profficient in MAP adjustering

I built my MAP sensor adjuster yesterday and need to figure out what voltage to put it at. Im hoping this will help with some less than desirable gas mileage. Is there any way you guys could take a look at my signature and recommend a good voltage at about 42-4500 feet elevation?

I measured my stock voltage to the map sensor and it was at 5.3 volts. Is it within the 5.0v spec or could that be causing some of my rich condition?

Try turning the voltage down, maybe in .25V increments, take it for a spin, and see how it performs.
