Dodgemech or someone that knows>>>Did DC program the car's computer to do any changes at 2,000-3,000-4,000-5,000 miles

Yep, there is language in there to change fuel/timing curves at different mileages. It isn't written in your owners manual or in the service manual. Supposed to be a pretty big change at about 30K or so.

 

Do you know the mileage at which the changes occur?

 

Thanks, for info Dodgemech>>>My Magnum RT has 2,000 miles on it now and MPG is still improving>>>>city 17 and highway 24-25 MPG on last 250 mile round trip at 70 MPH>>>>Only thing I did to Magnum was a K&N drop in filter element>>>I have no steering pull,rattles.pops,Magnum build date 10/04/04>>>this is a nice driving machine.
