I have an Edge Evolution CTS for gauge monitoring; it also has undeleted tunes. Edge upgraded it with a CTS2, but my CTS works fine and I can't see the cost of new and improved. I have to disagree with a few of the above posts. Towing heavy loads with a diesel (or gas) needs gauges. Pulling a long, steep hill with a load, I want to know if I am approaching 1200 on EGT's. I don't want to be notified when it goes into limp mode. Other critical areas are coolant and oil temps. To tow without being informed, for me, is risky behavior. I have it mounted, along with my TPMS, just to the left of the steering wheel and they are easily monitored, without taking eyes off the road. A quick glance is all it takes.
