ELectric Fans on a Cummins ?
For $600 or so FLex a lite makes a fan kit for the CUmmins 5.9 Anybody using it? is there a noticable MPG gain running empty? Does it work well enough to cool the truck when loaded?

Well you answered your own question. If you drive mostly empty, your fan should never really engage except really hot weather maybe. I can count on my hands how any times the fan has kicked on in my 07 unless I was towing or hauling something substantial. And my radiator fins are all smashed in thanks to my kids a few years ago!
Installing electric fans seems like a waste of time and $ for very little to no gain in a normal daily driver vehicle.
You would be surprised at how much your fan runs. If you run your A/C then your fan is constantly cycling. The OE fan is variable so you won't here it kick in 90% of the time because it only runs what is demanded of it. If this were me and I wanted to us electric fans I would just leave the OE fan in place and operating and then just add electric fans to help with the load. I would get a temp sensor rated at a higher value to add in and wire it so the OE fan will come on at a certain temp. Let the E-Fans do the light work like everyday running and A/C.
