I got all the same parts that get my 2nd gen 22mpg, and my 06 still only gets about 14mpgs. Am i missing something?
same with me, I have only been hand calculating for about 2 months now. I can tell you that my town driving average is around 12MPH and highway is 17 MPG.I kept a fuel mileage log for 3 years. Hand calculated average for entire time was 16.3. If I turn the programer to extreme, set the cruise on 65, it will get 20 mpg on the interstate. City driving kills my avg.
Good point. If my calculations are right there are 100 power strokes per second at 2000 RPM. Now if the timing is tweaked slightly it can make a big overall efficiency increase. I would never run stock timing ever, it's set up for emissions.....period. I hand calculate every tank and average between 21-23 mpg (US) with Bullydog 2.4ct on Crazy Larry....but that's keeping it at 65 mph.a good programmer will make a HUGE difference over the factory tune
