Fuel Mileage - Diesel Forum

Do any of the tuners / chips increase fuel mileage for the 6.0 engine or are they just HP / torque only?

Need to look in the 6.0 Aftermarket forum. There's enough information in there to keep your head spinning. [img]/ubbthreads/images/graemlins/laugh.gif[/img]

quick answer - Yes....
And No, if you USE the new hp/Tq....
which we ALL do [img]/ubbthreads/images/graemlins/smile.gif[/img]

let's say this, you can use mpg to justify the purchase to testosterone limited types, but it will never pay for itself in fuel savings [img]/ubbthreads/images/graemlins/smile.gif[/img]

It is supposed to but like said the extra power in used and then the mileage goes down. The overhead is wacked also, it is no longer correct since it is based on the fuel used thru the injector and with the chip you send more fuel thru and it cannot figure this out. You need to hand calculate it. It is worth it though. I have the edge 70hp/100ft lbs tq and i still see 16 in town and 19 highway under 2000 rpms and a rather level highway...really 18.7 [img]/ubbthreads/images/graemlins/cool.gif[/img]

So it works if you keep your foot off the pedal. MotionMan, how did the 3" lift affect your towing? I'm considering a 4 - 6" lift and will tow 9K at times.
