I know i have seen something like this before but i was wondering if there is a head unit, touch screen, that will show boost/gauges and other vehicle settings. Anyone know of one? Or am i insane?

 

That's called the Pioneer AVIC-N1/N2. I dunno if it shows boost, but it does show vehicle telemetrics (speed, RPM's, acceleration/handling G's?). Keep in mind they are far from accurate though...more for show.

 

well that depends on what gauge you are referring to. The gauge on the n1 and n2 are pretty accurate acually. Although neither has a boost gauge. The n1 or n2, has a voltmeter, which works prefectly, a spedometer with in my car and my buddies car is right on to the 1 mph, and there are other meters as well. Lateral forces and some others...

 

theres also and add on box that will give you more...
you can also add an hks camp to a video screen, there is a boost module you can add to it
