    HELLO! Im new to this website but seems to be very interesting. I have an '07 KENWORTH W-900L with a MXS C-15 ACERT engine rated at 475 hp. Followed by a 13 speed tranny and 3.36 rears on low pro rubber. Im planning a trip to see some PDI reps in Charlotte next weekend about a Stage 1 ecm tune. Is they any good info or advice as to what I can expect as far as hp, torque and fuel mileage? I average about 5.35 or so, but would love to get to 6 mpg. Any thoughts??

    I'd advise you to drive on past Charlotte to northern VA and let Mr Haney do your ecm work. He's an authorized PDI dealer but he's also one of the most knowledgable electronic Cat guys you will ever meet.

    Rob in Charlotte is also a good guy to work with. He's the only one who ever offered me a money back guaranty. Rob and Mr. Haney work together a lot from what I've heard. Either one can get you at least a mile to the gallon and a lot of power! There are several threads on this site with all the information you could ever need to get the most from your MXS. There are many options from many companies. My tune is PDI but I have friends who have Bully Dogs and other tunes that are very good.
