RE: About isx
Your post implies that you want to go up hills faster which is the exact opposite thing that needs to be done for mpg's.

We need a bit more history and information about the truck and trailer you normally pull, your driving habits, the normal freight that you pull, areas and regions you're working in... just more than you have a truck and an ISX if you want to start learning how to properly drive heavy freight for a real profit and saving fuel.

As far as after treatment maintenance go to the home page of this site and type EGR tune up in the Google search bar. Also check out Rawze's egr tune videos under the videos button.

RE: About isx
like chamber said, we can't read your mind, need more info on the truck. year, make, model, what transmission/# of gears, what's the rear end ratio.

What are you pulling? van? reefer? flatbed? specialized?

Lot and Lots of Q's. Read up on doing an EGR Tune-up. Also take a quick read through "My Book linked at the top of the website. Lots of good info for buying and starting to maintain a truck. As far as regular maintenance that's a good place to start.
