Ah... it may be working fine. Air in the fuel line can make your FP gauge twitch. Some boost leaks do the same thing - it twitches.

I figured it was something like that. It doesnt move all that much anyways, just noticed it because I was looking at it the entire time to see what it was doing.

I agree, you don't want to program out what you want to see. If anything, I'd want the speed increased for the fuel pressure gauge. I think the reason it looks glitchy is because it takes readings too far apart. Increase the frequency of samples and it should be more of a quick sweep instead of a jump. The temp gauges seem to be smoother because of how the heat transfers to and from the sender.

Rich, any input there? I don't have the software, I just downloaded and read the instructions a while back and am going off of memory and assumptions.

The fuel pressure regulator is not a precision instrument, it's a spring with a plunger-ish thing. Small movements are normal. You can program the sensitivity down to compensate, but that would negate seeing a pressure plunge when the power pedal is profusely pounded.
