Default Oil pressure lower than normal after some hard runs.. Suggestions?

I just put in my new forged 347 a few weeks ago and got it tuned. Runs awesome. I've got about 250 miles on it now. I have changed the oil 4 times so far.

My oil pressure at idle has always been around 40PSI and 75PSI at WOT. I went out to a car meet last weekend and did about 5 or 6 hard runs with the car and now the oil pressure is at 20PSI at idle and Fluctuates from 40 - 45PSI at WOT.

I don't hear any abnormal ticking or other motor noises and the car still has TONS of power.

I changed the oil today to see if it brought up the pressure any and it didn't. It still idled at 20PSI and was 45ish at WOT. Considering I am spinning my car to nearly 7K RPM I don't think 45PSI is going to cut-it.

Could it be a bad oil pump already? I am open to suggestions of what to check or do next.

Cut the oil filter open and inspect the filter element for bearing material.
