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??
Any Helpful info or advice on tuning a MXS C15 ACERT engine...
