boost guage questions

[luke]

you guys were right... the guage is in two different units...
so it is reading accurate :) i seem to be getting about 5.8 psi too so all
seems to be working perfect.... now to drill a hole in my passenger side
dash... OUCH! (im pretty scared to take a drill to my interior)
i plan on mounting the gauge directly above the quattro badge above the
glove box...
i dunno...
well thanks for the responses guys...
im glad to know it was just me being stupid and not my car being messed up
:)

went racing again this week... my speedo doesnt work but i estimate my
0-60mph at about 7-7.5 seconds... its amazing what 141hp in a 1750kg car can
do... :)

thanks
