Hey Mark, good to see you last night. Agreed that it would be good to know the fuel pressure. You can see in the video and also in your data log after running through 1st gear that the AFR goes extremely lean "Cycle A/F", and the injector % over 100 that you are probably out of fuel pressure.

Not sure what pump setup you're running but it sounds like an external pump.

I think you're probably a great candidate for the Aeromotive Phantom 340 lph pump - you can either put this in an original tank (dried out, filled with water before drilling), or a brand new tank so long as it has some flat spots on the top. Otherwise on a new tank you can always fabricate it. Make sure you do a bypass regulator after the EFI if it allows and use at least a 3/8" feed and return.
