Shimmed my oil pump.. went from 35psi to 45-46 psi..

Sounds perfect. I just re-shimmed mine.
That was my original goal, between 40 & 45 at operating temp.
I went from 7 Canadian dimes 0.334" to 8 US dimes 0.414 and have basically the same pressure at operating temp you have. I'm at 22psi at 700rpm 210* idle.
I was hangin out on mumble with Rawze, and he mentioned that the rod and mains can get washed out at 50psi or above. So anybody performing this mod, be damn sure you warm your truck for at least 15 minutes after this, because with the oil temp at or below 150* the oil pressure will easily climb past 50!!!
People performing and operating engines with modifications need to be attentive and responsible in order to maintain longevity.
