thetruck, as soon as I have the Phazer back on the dyno I will give you some information. Both the Apex and FX Nytro with fuel injection stock have been around 53% injector duty cycle. With a larger volume fuel pump you should have no problems with E85.

Wow, it sounds like they are oversized. Do you know if the injectors are the same for the three sleds? If there is that much room on the injectors we may not even have to worry about upping the rail pressure.
