So I've had my car for close to a year now and drove around AFR blind. In February i purchased a PLX Dm-6 wideband and finally got around to installing it. The idle/crusing numbers seem good from what research I've done, at 14.5 - 14.7. The WOT numbers are 10.8 - 11.2 which seem a bit rich. Car runs really good. What are some thoughts? Do I need to worry?
