Which Guage to Buy??

[HotAirGN]

Since its time for guages in my car I'm geting water and oil on the console and then a have a dual A pilar pod. Question is what should go there Boost and what. I am torn between A/F or Caspers knock guage. Which is more important or just better to have, thanks

I like the knock guage...
Since I monitor the boost guage more than anything, I mounted
the knock guage right next to it.
It's easy to see and could save you from hurting parts,
especially going down the racetrack.

Why not get them all and have them placed where they should be?
