New to boost so bare with me, but I'm supercharging my 2.4 and looking for a a/f gauge and my buddy is telling me I need a a/f controller for the gauge, he doesnt work on domestic. is this necessary? Or just need the gauge

 

Depends on the gauge. Some come with a controller some dont use one.

 

A controller for a wideband gauge?

 

my LC-1 uses a controller

 

AEM Uego doesn't. It's all in one.
