today is the first time I got to drive in the day light with "econo mode", and I call bull **** on mpg gains. The black smoke does not ****ing stop pouring out with anything more than about 1500 rpms, with that being it still goes faster from a stop with rpms < 1500 than compared to stock. I might just have to keap it in "tow mode" which is like 20 hp boost or something.
eight- most of my buddies with 6.0's get 20+ on the highway and around 17-19 in the city, although they have that fancy MPG reader in the over head consol that might be filling them full of ****.
