Mine drops into the upper part of the (m) when idiling especially after coming off the highway. Then it goes back to halfway when I start moving again. It's been that way ever since I have had it so I believe that is normal.

The factory gauge kinda sucks anyway...mine got stuck. My amp gauge has never moved in the time I've had this car either.

Factory gauge sucks, and sender can become inaccurate also, usually indicating lower pressure as it ages. And that assumes the IVR is operating correctly. What all this means is that comparing the gauge on one TC to another TC means NOTHING. If you are concerned about oil pressure, put an accurate mechanical gauge on it.
