Running LEAN! 96 5.0
Just got pillar gauges hooked up and one is an air/fuel ratio and it's showing I'm running very lean and it misses a little in the high rpms and I'm clueless any idea? It gets like 9-11 mpg

You can't have both a lean motor and 10mpg something doesn't add up.
Where do you have this wideband gauge hooked up? Does it have it's own sensor or it is connected to the truck's sensor?
Has the gauge been calibrated?(if that's even an option)
Does it show lean all the time even at idle?

There's a racing shop here in town they hooked it up, it hooks up to the trucks narrowband o2 sensor according to the instructions and the gauges are from glowshift.

That gauge is basically useless with the stock narrow band sensor. The sensor only output's 0-1V, 0 for lean, 1 for rich. VERY imprecise. It just constantly switches between the two to balance out to the proper mixture. Chances are, it is BARELY lean if at all, but the gauge sees it as WAY lean. If you want it to work, you will need a wide band O2 sensor.

Is the gauge an actual wideband gauge with numbers on it or does it just have Rich/Normal/Lean indications? This second type is what should be used when connecting to the stock O2 sensor, the other type will never work right because it's expecting to see 0-5v not the 0-1v range the stock sensor generates.
