There is another possibility for losing pressure at higher engine speed and that's an over-filled sump and the crankshaft frothing the
oil (aeration). I experienced this in a Pontiac I once put too much
oil in by accident and it was fine until I settled in on the highway and then it would start to lose pressure and the pressure would fluctuate.
