Quick Fuel Slayer Rich!!!! installed LC-1 wide band

AFR gauges aren't always accurate at idle. For idle purposes, go by vacuum reading (and plug color...if it's pig rich, you'll blacken the plugs).

Main jets won't affect your idle, but the Slayer has replaceable idle air bleeds and idle restrictors.

To check your idle circuit, drive the car at a steady 40-50 mph and take an AFR reading. To check your mains, drive a steady 70. Take a reading there. If it's rich at 40-50, you'll probably want a smaller idle restrictor or LARGER (edit) idle air bleeds. If it's rich on the mains, smaller main jets (or larger bleeds).
