Nice but personally I prefer Turner's P3 vent gauge:

It's a little pricey and the install is difficult enough that I'd take it to a shop so that they can deal w/any problems that arise (particularly in attaching the vacuum line to the charge pipe for the boost gauge) and "fix" any plastic trim pieces that might break along the way. It's not essential to me but I'm still thinking about buying it just for the "bling" factor as well as for the info it can provide.
Would probably buy it pre-installed in a vent, which would cost more, but would make it easier to install and remove/sell later. In the meantime, I can use my Cobb V3 if I really need to read/monitor any gauges.
