{"text":"Does, or has, anyone used this? How accurate are the MPG calculations? This T660 has one on it and I went online for the manual so I could reset the trip/mileage data.

I've read on here that the ISX likes 1450rpm, but it seems this one prefers 63mph...(ugh).\nI suppose I should mention I'm a flatbedder hauling mostly farm and construction equipment.","pics":"[]","canComment":true}
