3 bar map sensor incorrect voltage

In troubleshooting an issue with my MSD 3 bar map sensor I noticed the Map signal wire constantly reads around 5 volts when plugged in with key on engine off. When I plug the stock map sensor in it reads around 2-3volts. Does this mean I am using the wrong scalar?

Does it read correctly when the car is running?

Oddly enough the values in hondata barely change. The most I have seen it move was .5 psi to .6
