Pat - did you check your max fuel flow at any time - to see if fuel rate was a limiting factor.
I agree - if you lift the system pressure and the WUR pressure , you have not achieved much.
But the Q is why is it leaning out so much, and so rich at the WUR dump. It would suggest your head is running out of fuel supply around 4500 rpm. You are 'only' about 25% more hp at max revs than a 204 hp SC - so it does not seem right to be running short of fuel supply at 4500 rpm.
