So have you sprayed the truck with the 20 jet? If so what did you get on a/f? If you haven't sprayed the truck yet then i would suggest not going with that low of a jet until you see what your truck likes (progressively drop jets by 2s, try 28, then 26 etc..). Also what kind of pump are you running and what all safety equipment do you have?

Start off with the recommended jet and work your way down from there. Don't go off the a/f gauge, go off the plugs.

Twotonefreak is absolutely correct, the plugs will tell all. I don't use an a/f gauge. They are a good tool for tuning but they can't tell you which cylinder is the leanest since they take a cumulative average. If you talk to some of the heavy hitters spraying over 300 they will tell you every motor reacts differently, some like to be a little richer and some don't.
