[QUOTE="TRBO VNM, post: 14530971, member: 14678"] Ported eaton 4# lower 60# injectors stock MAF with mafia stock pumps with BAP and wire upgrade JLT RAI Logging the car during a pull fuel rail pressure is dropping and actually gets down to about 14psi. A/F stays in the 11's until it hits that low and spikes to 12.0 or so and then drops back down in the 11's. It's like the pressure is fine at idle, once hitting the gas is starts dropping and is at its lowest point in the 4000-4400 range and then comes back up, but only to 22 psi. Based on A/f the car is doing what it is supposed to and opens the fuel injectors to try and maintain the a/f. Pressure drop across injector also drops as I would expect based on the FRPS readings. Doesn't appear to be belt slip and if so, I would assume it would show rich and not lean? FPDC is 84%, so I wouldn't think there is a pump issue or hole in a hose in the tank. Fuel filter has been replaced. Only other thing I can think of is socks on the pumps? I am stumped and that rarely happens. LOL [/QUOTE]
