roush boost gauge install

[TXSVT1]

Vehicle 2013 a6 with vortech
Installed my roush boost gauge and have a couple of issues, first got it hooked up and working properly but it glows blue all the time so I'm wondering where do I hook up the white electrical wire so I can get it to glow white?
Second is the gauge was working perfect until I installed my torque booster and now the gauge won't read any kind of boost at all. Only vac. It's not the gauge bc it was reading properly before the torque booster install. Didn't switch anything on the vac site for the boost gauge after the torque booster so it can't be the site. Puzzled so open to suggestions. Thanks

I'm looking into getting this same gauge myself. Take a look at the wiring chart at the bottom of this PDF, hopefully if will help with the lighting issue:

Got that part figured out. Now I just need help figuring out which vac point to use for the boost.

AFAIK, your only choice is the BOV line. That should be fine.
