I don't know anything about how the Holley stuff works, but is there a setting that tells it what to look for as a point of reference when it powers on?So, when you power up your ignition, without start, your map sensor should read 98-99, and it shows 129. I can change the map sensor from a 5 bar to a 3 bar and it gets close..... something isn't right though! I thought maybe the efi had the map scaling wrong so I manually built my map with values provided by lowdollar, no luck! It starts and runs, but it's super rich.
