I've recently installed an Airaid intake on my 14 v6 and noticed the air/fuel gauge spikes up to 20 when I let off the pedal. The gauge normally idles around 14. Is this something that I need to be concern with...(no tune, yet)?

Thanks for your responses.

First thing is first...

What is powering that gauge? What model wideband AFR meter and sensor do you have? Please answer these questions.


Now to answer your question: It is not unusual at all to see VERY lean readings while decelerating.

Well, this gauge comes stock with this model. I did not install an AFR meter.

Ahhh... In-dash. I neglected to look and see which forum I was in.
