My car has had a Brenspeed 93 octane tune on it for about a year. I just installed a Aeroforce Gauge, and set it up to display the AF ratio. I haven't had a chance to go out and run the car hard or at wide open throttle to see what it reads, but I will soon. What is a typical reading from a gauge like this connected directly to the OBD II port while just sitting their idling? My gauge is showing high 14's while idling, which I am not sure is normal.
