Im running rich, New Wideband o2 sensor tool/toy Options

[Andyrew]

Ok after I made the device for the wideband to attach to the muffler (pic if you want it..) me and dad tested all the p-cars with the new wideband tool from Innovate motorsports. He bought it so dad can tune his racecar when he gets the piggyback system working.
Sweet little tool!!!

But it shows me that I have multiple problems. Im running a little rich. I thought I was not getting enough airflow, so I cleaned my air filter but that didnt do much. I took off the airbox, but it was just a tad bit. Ok, I should be running 14.5 or so parts air to part gas. But im running 12.5 at a steady 3k. Idle is eratic.. I turned the knob down all the way on the ECU yesterday, and it helped a little. but I went to start my car today, and it wouldnt run with the AAR closed.. So I raised the ECU knob a little and that fixed it. Under full throttle, (Even though I dont get max hp) Im running about 12.4 or so A/F ratio.. Which is good. ..

So, what do you guys think I can do??
