Hi all,
I've only put 124 miles on the 4500 but I've noticed the overhead fuel mileage come up over a mpg (around town) to 12. 3 mpg. The seat of the pants feel is a little more responsive and a little quicker turbo spoolup. EGTs are the most noticeable dropping from almost 340' to a little less than 300' at idle and about 275' drop while cruising level at 70 mph unloaded.
I haven't been driving it because I'm installing air horns on it and have made a rocket science project out of it. Right now I'm stymied on getting to the factory horns, well hidden behind the fender liner. I may see if I can trace the wires into the cab so I can tap them in series w/ switch in the cab. Anyway, it might be evening or to to finish.
Happy trails, Wiredawg
