Just got 2005 crossfire roadster with 8000 miles on it. since 2005 have there been new updates done to computer? if so are they available at chrysler dealerships? and how costly would they be? are they covered under extended warranty which I have?

 

I don't believe there are any updates from Chrysler for the computer. You can get performance modifications (tunes). There are a couple of recommended vendors out that can do this for you.
