^Jay, I was going to bring up Zietronix as well...but I think the boost moves too fast for you go read. The zeitronix is great for datalogging, like you said. Several of my friends have them in their Evos, but, like you, in addition to the Zeitronix, they have a boost gauge for an easier way to read the boost reading.
I thought about going the Zeitronix route, at the time, it would've been cheaper than getting all 3 of my Defi gauges, the gruppe-s panel for them, and control unit...but the Defi's do look cool and are very functional
