Tuning the boost WGSDuty on a GT30R and noticed the BARO reading doesn't stay constant. It actually decreases as boost and RPM climb. Also noticed Battery voltage drops just a touch.

Omni4Bar is wired into MAP input
ZT2WB is wired into rearO2 (but the sensor is currently dead, so the reading is pinned to 15.3:1)

A few months back I had a no-start condition that turned out to be a poor +5vref connection for the factory MAF.

Maybe I need to rewire the MAF connector (or the +5v line at least)?
