Like my signature says, I went with ISSPRO guages, based on response from the DieselStop forum. There are cheaper, but these will last forever.
The boost gauge merely tells you how hard you are being pushed back in your seat (when NOT towing). But it also tells you when you are consuming fuel. No boost means driving using little fuel. My transmission guage mounted in a test point in the transmission. I had my BIL, a machinist, come and drill and tap the hole for the Exhaust Gas - that was a little trickier than I wanted to do. I could have bought matching paint for the pillar but it was maybe 10 bucks. I got a pretty close match at Wally World $2. The entire job took me 1/2 day, plus a couple hours for the BIL's work. (That cost me a couple beers.)
I was surprised at how hot the Exhaust gasses get, and how warm the tranny will get on an extended run during the summer. Well worth having the guages!
. Both these digital gauges come with a cable which simply plugs into your OBD II port. The Bully Dog allows you to review trouble codes and I believe clear them too (not positive), I don't know if the Edge does this or not. Both of these products will give you what you what. Both of them use onboard OEM engine transducers and sensors, so installation is not difficult. I believe the Edge unit is a stand alone unit, in other words it has it's own housing. The Bully Dog requires you to purchase a A-Pillar mount and paint it to match your truck. All this being said, I still think the tri pod A-Pillar analog round "steam" gauges just look plain neat ! However, as has been stated, the digital units give you way more data to keep you occupied while Donna naps on those long trips. Try Auto-Zone for the Edge they sell them too. Hope this helps.
