I've been working on a clock replacement for my 165 for a while. I wanted to integrate a boost gauge into the clock but then decided not to because the clock is kind of a distance away and not really easy to see while driving. I had made this boost gauge already though:

Here is a thread over at MR2OC I started which had input that sparked my interest in a more complicated gauge:

Basically the complication was that without another pressure sensor to reference, if you ascended, the value read by the electronic boost gauge would be off as you climbed in elevation (Since atmospheric pressure drops). This goes for most MAP based fuel injection systems also. If you are confused, take a read here:

Does this mean an analog gauge sucks? No, it's just not accurate. I wanted to make a boost controller/gauge using a barometric sensor to properly regulate "Real" boost, to avoid blowing my engine while I climbed steep hills. I live at around 800ft but I drive to my cabin every other weekend which is above 6000ft.
So I made the altimeter that will eventually output a signal to another Arduino boost gauge. I am working out the final wiring diagram so if you guys ever want to make one yourself, you can. The buttons are replaced with a single aluminum bar that acts as a capacitive sensor. so it's touch sensitive to switch between the screens. I might sell a kit with everything you need including all the 3D printed parts to hold the screen and sensors, you would just have to do the soldering and wiring. If you're good at programming you can change the fonts. The splash screen is also very easy to make, I whipped this one up in MS Paint in about 20 minutes. Here are some quick shots:
