Why?

Oh cool, you ended up going with the Mod Man? I've been away for quite a while and haven't kept up with everyone's projects. I remember you were considering it as one of the few carb options out there. I had a hell of a time trying to figure my carb out. Had a Carter AFB that was rated at 625 cfm, which should have been plenty for my bone stock 5.7. It would cruise pretty nice, but just didn't have much punch at WOT. I played with jets some and rigged up the stock O2 sensor to get a rough idea of what was going on (simple little circuit that had LEDs for rich or lean), but never quite figured it out. If you went full throttle from cruise it would flat out fall on its face and almost die. If you rolled into the throttle it would pick up okay, but just never had the top end I was expecting. Played with several jets and rods and was never happy. Looked into getting another carb and ended up finding the Megasquirt instead.
