Then it seemed to stay there for first 10 minutes of drive and then at a red light it dropped to 40 psi per gauge.
Parked truck after 20 minute drive and at idle in gear had this:

That is what my '92 does. Similar pressure at idle, too. Cruising down the road it sits at about 45-50. Idle is 20-25. I don't know what the '95 is really. I should get that gauge hooked up.
