Junk equiss gauges?

Was out for a putt in the barracuda and noticed my oil psi was up past 80 and hitting the 90psi range at the end of my ride so it got me thinking why it was so high. Normally 65 to 75 psi range. So I just parked it becoming frustrated. Then today I went to assess the issue and noticed the gauge was at 20psi and hadn' t started it yet.
Total junk!
I'm gonna look into some mopar gauges to replace em. Anyone thinking of buying the equiss gauges, stay away. Waste of money.
