I bought an Ultra Gauge a couple months ago used. I like it. Nice big screen and six gauges at once is nice. It does just about all that a Scangauge does for half the price. Mounted mine here, just enough cord....
I had both. I don't like that the UG has a permanently attached cable and at the time I bought mine it was slow to read the truck. I'm running an SG again and I like it. No alarms like the UG though. It does have a performance tracker mode though.
I like both but in the end I prefer the SG because of trans temp and the detachable line. They both do the same other than that so it depends on what's important to you.
I have to find a place to moun it. I like the above the mirror look, but i installed the relocation bracket for my RV mirror so it sits flush with the headliner now
