2G Boost Gauge vs Omnipower Map Sensor

[Mham2k]

I have an old autometer boost Gauge that was in this car when I bought it and a new omnipower 4 bar map sensor that I installed about 6 months ago.

The boost Gauge is consistently 5 psi higher than the map sensor.

Example boost Gauge 20psi vs map sensor 15psi.

Which should I trust?

id trust the map sensor over the gauge. gauges go out of calibration and will read incorrect.

Not to thread jack, but how about when the boost gauge uses a MAP, like the Innovate MTX boost gauge I have, and the omni 4 bar from ecmlink doesn't work at all regardless of how it's hooked up?

I'll make my own thread once I've done more testing, but I wouldn't just automatically assume the omni is right before checking a few things.

My Omni worked out the box just put it in place of the MDP and configured link.

mine is a 1g so no such luck on a factory map spot. i expected it to work out of the box as well, but i may have a setting wrong or just a bad map/PnP harness.
posting new thread now.

You can check your sensors to see if they are performing within spec. Attached is the specification data for OMNI-Power Map sensors.
