2002 3.2 oil pressure oddities

Driving home from a bit of a road trip today, I was cruising down the freeway at about 3200rpms and noticed my oil pressure gauge doing odd things. Generally, the pressure shows normal around 45-50 PSI. However, it would randomly spike up (once tapped 8 bar) and then settle and be fine. Oil pressure at idle is normal, car runs fine. It is ENTIRELY possible it has done this since I installed the gauge, but not noticed it. I just happened to see it happen this time. 996 sender is relatively new (1.5k miles). Prob not an issue at all, just wondered if anyone had any thoughts.

Those sending units are very unreliable.

That's a smart idea.
I ended up just getting the 14x1.5 VDO sender.

996 sender is a rebranded vdo unit, yes?

Thatís what I thought too. Perhaps the better solution is to maintain the single dummy light sender in the stock location and place a dedicated pressure sender on the other side. Is it the pressure sender itself that is troublesome, or the dual unit in particular?

I have a VDO guage...
