This made it possible to run my 2 bar MAP sensor, but it did take some tuning work by the ever reliable Holley customer support crew.

Should come with better instructions for tuning the map sensor and a list of common map sensor part numbers and their respective values. However, most of that information is able to be found online with a little patience.
