Gauges are very important with a tuned truck.
you can get analog gauges and you can pillar mount them, and you should be able to overhead mount them even with the sunroof.
I will make a suggestion juts for simplicity, Edge has a product called the Insight, its a digital all in one gauge setup up that has a nice dash mount that goes under the driver side grab handle (so you don't loose your handle) and it monitor up to 6 parameters at one time, although the 4 parameters at a time is about the best setup up. You can monitor things such as boost, oil temp, water temps, trans temps, pryometer, etc, etc..
The Insight is also a datalogger, it can pull DTC's (diagnostic trouble codes), simple performance testing such as 1/4 miles times 0-60 times and a few others. Also the Insight can be setup by the user to alert you if a desired "limit" temperature is reached, the screen will flash. Also it has a multi color screen, you can set it to whatever you like.
With that said, you will absolutely get your best bang for you buck when it comes to gauges with the Insight, you could easily spend $2k in analog gauges trying to duplicate what the Insight does and still not have it all. I have the Insight and 7 analog gauges in my personal truck and I love the Insight just because of how simple it is.
We have a package available for $430.00 shipped that includes the Insight, pyrometer probe, dash mount and a can of paint for the dash mount.
