I just got my juice/att combo for my 600 and installed it today. When I first started the truck it idled rough and check engine light came. Took it for and drive and it ran terrible on all settings. When I steped on the throttle it just fell flat on its face. It was poping like a misfire but didn't produce any smoke. I know all my connections were right. When i took the box back off, the truck ran like normal and engine light went off later. Anybody have any ideas. Gotta wait till monday to call edge.

Thanks in advance

Just to check the MAP sensor plug, sometime they are easy to plug in backwards if the plug does not have the keys on it (though I have never did it) - That would cause some seriously bad running

I had that happen on my 3rd beta box. It was a bad box. Returned it, and no further problem.

I have the juice also, my check eng light came on also,but went out after the first five starts. What I mean by that is when you first install it and you crank your truck you have to accept the aggrement on the attitude, and after that it went out. As far as the falling on its face, was the engine still cold? I know that it will not give you any power until it reaches opperating temp. Just my $.02
