Gotta make a long haul empty, was wondering if it would be best to put my truck back to stock (remove bullydog) to get the best fuel mileage, or should i just leave it on teh current highest setting? Thanks

I believe most programmers increase fuel economy at lower power levels.

Leave it on and drive it like it was stock. You should see an increase even in the higher settings.

I took a little 500 mile trip and got hand calculated 21 mpg on the 95 hp setting :ro)

Does your truck rattle up a storm in the morning when it's cold? I just installed a Bully Dog power pup in mine and it rattles so much when cold I'm afraid I'm damaging the motor.
