I was reading on of the the stickies that it was recommended to get one of these when starting to mod a GTP.

I was all for it until a friend of mine's Regal GS got broken into at the local mall and the only thing they stole was the interceptor from the A Pillar. Is there an alternative to mounting them on the A-Pillar or another device that could log and monitor things like Boost pressure and KR?

It sounds silly and to be completely paranoid about one event but I'd like to know of my options before throwing down money.
