    Just wondering if you other guys who have done this install had experienced something similar. I removed a 4 bbl Carter AFB to install the Pro Jection. The Jeep ran just how it should with the 4 bbl on it, torquey and quick with plent of power. After the F.I. install, it's really gutless, can't even pull a mild grade in 3rd gear (T14) much less use the OD in 3rd at all. I didn't change the timing, the plugs, or anything. Just the F.I. It seems to run fine and I do have the closed loop kit and the A/F ratio meter installed. Any thoughts? You guys always seem to think of something I've missed.

    not familiar w/ the projection, but my first thought was are you getting enough fuel pressure to the unit?

    Pretty sure there is enough fuel, I am using the upgraded pump that Holley supplies. I will mess with the mid adjustment and see if that helps. I will check the af indicator while it's doing the low power and see where it's at.
