Re: Adding a boost guage to the S4/S6

I put mine under the left air vent near the steering wheel. You can also mount
it where the ash tray is, or at the bottom of the A-pillar if you can find the
right mounting cup.

I used a small (?1 1/8") VDO 0-30psi boost guage. Ned recomemded an absolute
pressure guage (aircraft type), but the VDO was cheap, and the fancy one was
~$125. With Ned's chip, and the right weather, I cat get up to 19PSI peak
boost (that's above the 14.8PSI atmospheric(1.0Bar), or around 2.25Bar.

Run good quality braid covered vacuum hose from the guage  behind the
carbon(wood) trim, under the dash, to the vacuum line going to the computer in
the floor of the front passenger side. I used a Y connector on the vacuum line
coming from the manifold to the computer, and kept the routing entirely under
the dash. It's simple, but time consuming because of the routing. I kept it on
the cabin side of the fire wall.
