Wideband Issues
 

AEM Wideband installed and when i'm at idle it reads 16.0. When i give it gas, it drops down, as low as 10.0 once when just reving the car. Toyed around with the SAFC settings so it doesn't dip much below 12 now with the car still on stands, and i know i'll have to do a better job when the car is on the ground. But is 16 the highest the guage goes? Or do i have to make some change?

FPR may be in my future as well, 255 high flow might be causing me to run a bit rich.

I believe it reads up to about 17. It will climb to it's top reading and then just illuminate the end of the sweeping portion of the gauge.
