Was reading about the Mileage Max anyone have it on the 2006 ctd ????? i have the cat back magna flow 5" system with the 6" tip....just curious if its really improved fuel mileage??? plus it says it leaves no foot prints ny comments on that?

 

Just ordered one...let you all know in a few weeks...Its for my uncles 06 1-ton 4x4 horse hauler...Most of the findings will be with our 26" Horse Trailer Goose on the end of the truck on the highway... but our last run cost us over $1000 in fuel from NY to FL and back, making a few stops on the way.

 

I have the X2 module with the MM program. Haven't seen much difference in daily driving but I usually can't get over 50mph in traffic for more than a second. TC never gets to lock. Quad says most of the MM gain is when driving Highway type mileage with constant foot pressure. Still glad I have it though.
