what all would i need to install a boost gauge in my tt and how hard is the process?

 

just get the awe tuning.com vent boost gauge. comes with everything and great install instructions! the hardest part of the whole process was gettin the wiper arms off!!!

 

I did an A-pillar boost gauge. Easy as hell.

You'll need to "T" into manifold vac, the short line from the fuel pressure regulator works well (under the long skinny plastic engine cover).
From there, route up thru the firewall, theres 2 or 3 places to do this, HERE'S a good choice, and all the instruction you should need. Thank Blue TTop from Audiworld for this one.
