Hey everyone. I was wondering if it's necessary to buy a WB AFR gauge if I already own a COBB AP and one of the options it gives me is to check my AFR. I have the COBB AP mounted to my center console so plugging it in and checking my AFR will only take mere seconds.

 

I believe that is your choice, my friend. If you are interested in buying one, please check out my link below. Thanks.

 

It's a good thing to have for when you are fine tuning the car. It's an analysis of checking out what kind of feedback is your car giving back to you on how its mixing air with the fuel. It's worth it.

 

Thanks everyone for their input. I might just end up getting one anyway. Just to be safe.
