If you go to Auto Meter's site and read up on them you will find that they only give an accurate (and I use that term "accurate" very loosely when talking about narrow band O2's such as the Auto Meter) reading at wide open throttle. The rest of the time it bounces around and means nothing. You really need to take your car to a dyno shop with a wideband O2 hooked up and at the same time and tune that way. I would suggest getting a custom chip burned at that same time or getting a tuner such as the "TwEECer" http://www.tweecer.com/ the PMS http://www.andersonfordmotorsport.com/ or one of several others out there and you have something that you can change your tune with as you need to with out having to pay for a re-burn each time plus you have a lot more things you can "control" and with something like the TwEECer RT you can even data log! Then you can get a wideband O2 and not even need a dyno shop! But anyway you really need to either get it to a dyno shop or do the wideband and tuner thing and find out where you are at AFR wise... Good Luck...
