I went with ISSPRO gauges, but am not sure I am in the majority. I like the looks of them and their customer service is good. The two most important gauges are the Exhaust Gas Temperature (EGT) or pyrometer, and the Turbo Boost gauge. Most others have opted for Transmission oil temperature for a third, but I went with fuel pressure so I could monitor not only the condition of the fuel filter, but also any other peculiarities of the pumps with all the talk about the lift pumps going out. I plan on getting a trans oil temp gauge in the future, but will probably mount it in a different location. My other 3 gauges are in the triple mount A-Pillar that still maintains the factory tweeter. For more info on gauges that others are using, try the search feature below the "post new topic" and "post reply" buttons.
And by the way, welcome to the family on this forum, and welcome to the owners of the best diesel truck this side of Caterpillar!
