The only reason I can see to measure the fuel pressure is to see if its on par with what the factory says it should be. I am not really inclined to increase it if its at "stock"

even the link you provided states without boost and taking advantage of the greater amount of fuel this will only enrichen the mix and harm my fuel economy. not improve it.

the evidence says the car is already running too rich (lower fuel economy)

IE if the test this weekend (mechanic confirmed he has FI Pressure tester on the phone tonight) shows me low I still won't have a reason to increase the fuel pressure. I will replace the bad component and test fuel pressure again.
