Bill when you were at 630rwhp, did you just have the stock pump and BAP?

Oh and again, I don't doubt anything Ron has told me, and I'm sure the car will come in at the number he stated. That's why I can't figure out how the hell I'm running out of fuel. He was even nice enough to offer me a refund on the BAP so I could go another route for fuel, or ship me a ZL1 pump asap that I could use with the BAP. He really has been GREAT to work with. I just wish he wasn't 12 hours away so he could get a look at what is going on first hand.

If anyone has any other ideas on how to make what I already have work, or what else to check in my setup I'm all ears.

Being that there is 17 volts available under boost at the stock fuel pump control unit on pin 1 of the connector when the pressure drops to 52psi, I have to believe I have everything installed correctly, and it's doing what it should be. I even went so far as to verify my prosport gauges were reading accurately by reading the actual value from the ecm for fuel pressure when all of this happens...it is about 3psi lower than what my gauge shows, so I am in deed running out of fuel.

The kicker to all of this is initially the fuel pressure did not drop...it took 900 miles for this problem to happen. Right when Mike has 90% of the tune sorted out, we have to put the brakes on tuning because of this fuel issue.
