Could your oil pressure concerns in any way be caused from your expanding the bearing oil ports?

I only removed the restriction, but maybe it needed to be there???

restriction = pressure

But I do have another issue that I think may be the high pressure bypass valve opening in the oil filter housing. I find at times the pressure drops. If I let off the accelerator pedal and the vehicle speed drops, at a certain point, the pressure jumps back up. I can then carefully apply the accelerator again and keep it a 3 bar.
