Boost pressure w/ GIAC chip
 

Just installed my Boost gauge over the weekend. Boost w/ stock chip measured a around 8-9 psi. Boost w/ GIAC chip measured 18-19 psi! An increase of 10 psi! Now that is what I call an aggressive chip. Hats off to Garrett. (Just hope reliability holds up).

Could you please post your hardware set up and where/how to mount gauge? Thanks. Also want one.

I agree..where are all of you mounting boost gauges at?? Also, who makes a boost gauge with red illumination?

Mounted the boost gauge in the left corner on top of the dash. I bought the Apex gauge which has a white face and a red needle. When it lights up, it is a blue indigo color. At first I tried to get a gauge that color-matched, but actually, I really like the contrast. The indigo blue really looks nice. Granted, the installation could look a lot cleaner if it was mounted in a pod or something like that, but it hides pretty well in the left corner and doesn't look unobtrusive. The dial is only about 60 mm in diameter. I will try and post pics later. (BTW I used simple black velcro to hold it down). As for installation, I tapped into the fuel pressure regulator line and ran the hose through the fire wall and up the left side of the dash. Pretty simple.
