That's ******* awesome. I love it.
What other gauge are you going to be installing? If none, why a boost gauge instead of something more "oh shit that needle shouldn't be at that point" type gauge? I mean yeah you can see the PSI, but at the same time... your butt will tell you when your in boost.
I'm going to be installing a a/f gauge also. I got the boost gauge so that I have an accurate pressure reading and know exactly what boost a particular pulley is producing when swapping pulleys. Plus it looks cool
