[QUOTE="6.0 Tech, post: 1565476, member: 23001"] Map should move based on however much boost you’re making. And I think that’s what the map obd pid is on your list. It would actually be boost. So at 10 psi of boost, map should read around 24.8, and the map that reads 0 should be 10. If your map isn’t moving, check the hose for attachment to either the sensor or the plenum. Also check it for a restriction by blowing thru it. If the hose checks out, you could have a bad map sensor, or a massive boost leak. We had one at the shop a few months back that we were dynoing, and it was laggy and Smokey. Put our boost leak detector on it, and the drivers side plenum was leaking so bad, our detector would only read about 2-5 psi on the gauge with full shop air being pumped into it. Also, do you have a boost fooler? Baro should only move as you go up or down in altitude. It’s not sensitive enough to pick up weather changes, but here in Phoenix, we read about 13.7-13.8 psi.
