Hey all, 2009 fxstb with derby sucker intake, d&d fat cat pipes, power commander V auto tuner. Been having problems lately using too much fuel. Took my plugs out and they smell like gas, so I'm assuming it's getting too much fuel? My mileage has gone down too. I have SE plugs and wires on order that will be picked up tomorrow. Wonder if that will help, or if I should ditch the auto tune and buy a SERT?

 

I have 2011 bob with the PC V, just V&H, I'm still working on getting it adjusted right. Based on the little experience I have with the system, I would say that you need to adjust you a/f mix, lean it out. In what throttle %, I couldn't tell you. I think the PC V is a pretty good system, but without a dyno and the ability to monitor it throughout the throttle range, it really just trial and error untill it "feels" right. Hope that helps. Best of luck.
