I am like every one else and trying to increase my mileage. My 02' has 107528 and I tow every day(lawn Service). I have KN filter and after market MAS air flow censer. I want a tune for everyday driving, and one for towing? I don't really want to increase the pressure in the trannie. I'm scared I will blow the transmission sense it has high mileage and it is slipping a little bit. I get 12 MPG in town if I drive like Gramma moses, 10 MPG towing my lawn trailer, and 14.8 MPG doing 77 MPH with the air on driving on the interstate. Is there anything I can do????????

Any tuner can pretty much do whatever you prefer. I recommend Justin @ Black Bear. Any good tuner will ask you exactly what you are looking for and tune accordingly.

I have the predator,running the 93Tune on E-85 w/my timing advanced 4 degrees.Im getting a steady 16.4 mpg @ $2.56 a gal.And the side effect....She Runs like a raped ape.

Does Justin @blackbear use efi live to tune the trucks

Does Justin @blackbear use efi live to tune the trucks

yes

o3lb - your truck should get better even with out the tuner. on the new trucks they changed the trans from 4 to 5 speed. so that would not be as comparible
am i right?
