Rear Main Seal

Alright,
So I got impatient and decided to take the Dart for a ride. All I can say is that it's a reformed smoker. No one wift of smoke. It's running great and no leaks! The only thing that I need your opinion on is that the oil pressure before I changed the main seal was about 30 psi at idle and 70 psi at about 5500 RPM. Now I have around 60 psi hot at idle and 90 psi at 5500 RPM. I have the Mopar Performance high volume oil pump. The only things s I changed were the main seal and the o-ring for my remote oil filter adapter (which I found was also leaking). Do you think that replacing the seal and o-ring could be account for the increased oil pressure? By the way, I am running Castrol full synthetic 10W 30 oil.
