I've had one on my 05 3500 srw 4x4,auto, 4.10 gears for about a month.
1st tank at 100 hp = 16.8 mpg
2nd tank at 0 hp = 17.4 mpg
3rd tank 60-70 hp in progress
All these are hand calculated as the overhead lieometer really goes haywire with the mp8.
Although not enough data to make a concrete determination my hopes of improving mpgs with the mp8 is not looking good.
