Wow! Similar setup to mine:

I'm actively working on my tune as well but power seems to be similar at this point. We both have a 6 speed/3.9 setup too and I see you're doing your pulls in 5th. I may give that a try to see how spool compares.

The Rev MS3 does not have +5 on the db37. It is possible it has it in the OEM harness (although I don't think so). When I faced this issue installing my MAP sensor, I opened up the MS3, picked an unused pin on the db37, and soldered a wire between the +5 supply inside the box and that pin.
Having the +5 that is supplied by the regulator in the MS3 is important, because analog sensors like this return a signal that is proportional to their supply voltage. If that supply voltage is 5% different between the A-D converter in the microcontroller and the sensor (which would not be terribly unusual), then your reading will be off by 5%.
