So I ended up getting the Ultraguage. I just couldn't afford the Scangauge.
*This review is not a discussion thread of Scanguage vs. Ultragauge.

So far I have logged 966 miles on the Ultragauge and I love it. My MPG's seem to be right on the money and the all the gauges seem to be reading where the should be. I had to do the distance calibration to get my speedometer correct. Distance calibration is absolutely necessary if you have larger tires or have changed gear ratios. The only issue I'm having is the fuel consumption rate and my distance till empty. Although there is a MPG calibration that can be done as well.
*When I did the distance calibration I used a GPS, they recommend using a straight road with mile markers, GPS is much easier.
The alarm features are great for reminding you when you need to change oil or get the truck serviced, but they can be enabled and disabled at the users discretion. Many of the gauges have an alarm associated with them. In the user manual they have a whole chart showing alarm setting and min and max values
For what you pay, you get a great product. I think once my average fuel mileage is dialed in my consumption rate and DTE will be fixed. The benefits of just having the trip meters and extra gauges make this a great value
The blue display works perfect for me since I have blue LED's in my gauges and buttons.
The OBD II cord is long enough so I could have mounted the gauge next to my rear view, but I prefer where it's mounted now
I honestly recommend the Ultragauge to anyone.
