Are you runnin an autometer guage, I've heard they aren't that accurate, unles you've got a wideband , but you can try turning up the fuel pressure.

A list of mods would help. You also might have a faulty sensor or two, which are causing issues (assuming your WB is working properly).

Good luck.

The range of a standard oxygen sensor isn't near that of a wideband but it still gives you a baseline. What is your fuel setup? All stock?

I dont know how much faith i would put in a gauge that doesn't have a wideband o2. If your really worried, bump up the fuel pressure some.
