has worked well so far have not pulled my travel trailer yet but my speedometer is right on now and have added about two miles a gallon on everyday driving.

It is easy to install, works well, and is easy to see. the only thing is I wish it had a oil pressure gauge as well.

I never thought technology could be so easy. So easy to install and just a flip of a switch an you can go from good economy to economy plus performance.The mileage keeps going up.
