Boost + vacuum. More information is always helpful. I chose the Cobalt gauges from Autometer for boost and a/f. They light up blue at night. I eventually plan on going with blue LEDs for the dash to match.

SD Porsche Fan,
Just curious if that AFM is wideband or narrow.....and what exactly is the difference between the two?
Also if any are using the A pillar pods, is there any permenant damage from installing one with a boost, afm mounted in it? I am leary of drilling holes and or modifications.

The Autometer afm is narrowband. If you went with a wideband you'd have to replace the stock O2 sensor with a wideband version.

It's a narrowband gauge. It merely reacts to constant voltage change from the O2 sensor. The lights literally scan back and forth constantly.The only practical use for the narrowband is under WOT throttle when you can actually see a steady signal and it should be in the STOICH area.
The wideband is able to give a more accurate indication of the AFR under a variety of condition as opposed to just WOT.
That said, I have the Ultra-lite boost/vacuum gauge and AFR.

Narrowband sensors were created for the purposes of fuel economy and emissions. They are a vague instrument for a turbo car looking for mixture information under boost.
