Thing is that I ordered a uprated pump where I got my engine rebuild, but I think it a bit low ..?

idle .............. 55 psi cold and 28 psi hot
2000 rpm ..... 40 psi hot
3000 rpm ..... 48 psi hot
raising to approx 52-55 psi hot when taking higher rpm's.

I dont know if it matters, but I have a external oilcooler mounted and i'm using a mobil 1 oil, (5w50) ??????
