Anyone with an 05' done this flash. Changes Rationality for several things.

Here's the link for it http://dodgeram.info/tsb/2007/18-022-07.htm

Any issues good or bad? What about mileage, any changes there? i want to get it done, but am afraid of losing mileage or any other good things i already have.

I do get the code P 514 pretty regularly (2-4 times per winter), Battery Temp Rationality, but doesn't seem to cause any issues.

Thoughts? Thanks in advance.

 

If the battery temp is your only problem then don't get it flashed as I've read of those who did flashes and were not happy with the changes and you can't undo a flash.
