When to reprogram?
Replaced wheels and tires a few months back, and the Chrysler service guy recommended I reprogram for the larger diameter and extra wheel weight.*
I went from stock 255 75 17 SRAs to 285 70 17 Duratracs and Tracker wheels.
Do I really need to reprogram? What's the best way to do that? I'm certainly not paying the dealership to do it, they try to rip me of every time I go in there.
I did notice my mpgs took a hit of about 4mpg. From 20 to 16 mpg. I figured that was normal and to be expected. Could I get some of that back by reprogramming?

I went from the stock steel 16s to a set of "S" alloys and 17s, and the speedo was off by a noticeable amount. The dealer could reprogram it, but I got a Flashcal and did it myself. Plus, no more reprogramming if I change sizes.
