I have an '03 GMC K3500 crew cab dually with the duramax (LLY)/Allison combo. I just installed the Banks six gun and speedloader. My average mileage before the upgrade was 12 MPG whether I was hauling or empty. Now I'm getting about 13+ MPG.
My mechanic was floored when he heard how low my gas mileage was. He told me I should be getting closer to 18 mpg.
What is everyone else averaging and if I'm low what could be the problem?
Thanks! Happy Holidays!
