Any dealer suggestions for warranty work near New London?

[bbksv]

I just got an f250 shipped here from Texas and its throwing some codes (actually thinking it has several problems)....and now Im looking for a dealer that won't give me a bunch of warranty hassle. It has about 58k on it and its an 07..so the warranty should be up later this year. It does have a tuner (Ill take that off and return the tune to stock) but the exhaust is a straight pipe with no cat.

Any suggestions??
