is scan gauge worth it?
I was interested in getting one for my 2003 ram 1500 truck.. I have a overhead readout that I actually find pretty accurate and if reset you can see instant economy. But i'd like to keep a running number for a tank and see the instant like what the scangauge does from what I understand.
Not sure if it's worth the about $200 (canadian) which would buy a lot of gas.
