I replaced the fuel filter with a high flow filter and put on a fuel pressure gauge. The fuel pressure is dropping to about 4 psi during the run. I also recorded the tach during a pass. It looks like the converter might be flashing closer to 3500-3600 and not 3000. It looks like it might be time for an electric pump.
Mechanical pumps have their limitations for sure and a good electric pump when mounted and wired into relays can last for years............I'd go that route and keep fuel pressure 5-6 lbs according to what needle n seats you run............
