Yes my speedometer is corrected with a smarty for the size tires and I am Hand calculating that all the mileage when I've done it and I have put it back to stock it changes virtually none what about the fuel in the intake I can't find anybody to address that problem thanks Monty

I have a 2005 Dodge Ram Crew Cab with 3.73 gears, 285-70-17 tires, no big bumpers, swb, level kit. Empty best mileage 15.5 with smarty jr. Bought the truck with Edge. Any setting only 14.5 mpg. 4" mbrp exhaust with muffler. AFE cold air with original injectors at 118000 miles, changed injectors(stock at 120000) no help, same mileage. Turbo looks good intake and exhaust no play. Pulled injectors sent back for check, pulled compression check at all cylinders in the 470 psi range. Notice intake was wet with fuel when pulled new injectors wasn't that way when pulled originals. On interstate at 1950 rpm 70 mph or a mixture of 2 lane at 55-60 doesn't seem to make and difference. With a 7x14 v nosed enclosed tandem axle trailer with 2 harleys approx 1450 lbs trailer weighs 2150 lbs mileage is 9.2 to 9.4 whether interstate or some 2 lane at no more than 1950 rpm. 2 questions: Why is the intake wet with fuel (never have seen a cummins wet, powerstroke yes), and why is the mileage so bad? Should have kept the old 93 Cummins! Thanks, Monty
