Low fuel pressure problem
I finally finished the install on the ECS paxton kit and have been working on the tuning and have come to find that the stock fuel pump is losing pressure over time. I have the boost a pump installed and set to max now but the AF ratio is in the 13's during boost and it keeps getting higher over time.
So one of 2 things is happening.. either the pump is just defective or the boost a pump killed it.
Has anyone had this problem before?
Anyone used the APS kit?

Having the same problem right now. What year is your car? Try filling the gas tank. In the newer C6's the gas tank is designed different. When the boost a pump is trying to force that much fuel, the bucket containing the pump in the tank has a hard time keeping up. See if that helps. If it does, that means you will probably need to get a better pump.
