IMO the gauge pod that is the most functional is the cluster surround. I personally have the cluster surround pod with my boost and fuel pressure, then I have my Uego in a single pod right on top of the steering column. It sits right in the middle of my tach and the only thing it blocks on the cluster is the little STi logo. I have had all the different pods but this is the most functional for me during track use. Its hard to keep an eye on the rpms then check boost/wide band on in the clock or pillar pod......then back to rpm's etc. By then you mis shifted lol.

as far as types of gauges, I love the AEM wideband. I have Prosport boost gauge and fuel pressure gauges but I don't recommend them. The fuel pressure gauge worked for about a week and hasnt worked since.......the boost gauge works ok but it is annoyingly loud when you first power on the car.....I have the peak series and it has a very loud long beep when you first power on the car
