That AC takes away around 3mpg. Plus with the heat it will cause your trims to go positive and add alot of fuel even though you dont need it. Have your tuner set the intake charge temp bias to 1 across the board thats a big reason why the people get worse mileage in the summer aside from the AC

those heavy *** wheels. are a big problem im sure. i only have 20s. they feel like having on big *** shoes.. id get rid of those things. go 22s if you gotta have the inches. get all you computer stuff together. the interns are designed to work together. you have to communicate that with the entire truck

Thanks again for all the feedback. I Might get rid of the 24's and get a set of tbss rims. I figure that should help a bit. I adjusted the speedo today with the predator and i figured that the extremely low mileage was due in part to that. I also have a new mass air(with the factory screen) on the way. Let's see if these changes help out a bit. I also need to read up on mv's and where they should be at.
