Re: any fuel economy data on the 6.4?
[ QUOTE ]
Been a diesel mechanic/tech[everybody is a tech today]for 36 years,seen quite an evolution of the diesel engine,been working on electronic controled engines since 1990,and yes they have cleaned them up dramatically,but in the last few years fuel milage has suffered due to emissions.Ask anyone that does this for their living and they'll probably tell you the same thing.Bar stool&keyboard techs/mechanics need not apply

They cut emmissions with all this bolt on garbage thus reducing fuel economy and you gotta burn more fuel!!! Sounds like an emmissions wash to me!
