September 3, 2011I recently put EFI Live on my LBZ Duramax and just thought I`d share some impressive numbers here...
Prior to getting it I was pulling about 18 MPG on the hwy and 14 in town
After getting it I get 25 MPG on the hwy!! and 18 ish in the city!
I am extrmemly happy with these results, I thought if more people know about the mpg potential from these diesels maybe more people will buy them becuase I get 9 MORE MPG than my old Silverado 5.3L! Too me that is awesome! And the power difference is insane, you could move a house and beat out anything at the stop lights!
Just my about it all, hope it persuades ya!
