I have contacted 3 dealers in my area ( east texas) and they don't even know about these problems with the 600. How do you proceed with getting the reflash? Does your truck have to be "recalled" or do you just take it to a "knowledgeable" dealer.

 

A knowledgeable dealer is always the key. Tough thing to come by. I suggest having them actually look in the system for the reflash instead of just having them say that they haven't seen the problem.

 

bigblock2stroke, what do you think about the fuel economy of the new "600"?

 

It's worse than the 555.
