Air/Fuel ratio gauge readings
 

I'm running a Holley FMU on my turbo kit. My air/fuel gauge is allways reading rich when I'm cruising along. Do I really want it at rich or should I try to adjust it to run a little more in the stoich area. And how can I make it run a little less rich, will a fuel regulator do this for me? Thanks

Leave it rich. A lean fuel mixture from an fmu means "boom" no more engine.
