Have you verified with a mechanical gauge?

No, but I'm almost sure the stock one is operational. I know the rule is 10 psi for every 1000rpms and it idles at about 700 so its probably ok?

Operational, yes, but may not be accurate

Could be a bad sender. Or wire is bad.

Yes but what is it is accurate is the pressure ok?
Who knows? It's probably fine, but if your gauge reads 10 lbs high,because it's inaccurate,then no your pressure is too low. I wouldn't bank on the gauge being off,but nobody knows for sure. If you aren't hearing lifters clicking you are probably just fine.

As @Ricko1966 stated, probably fine, but it does need to be verified with a manual gauge
