I put 315 on my 2004. 5. I called the local dealer (west Covina Dodge, so. calif) They told me it would cost 86. 00. I then contacted the dealer I bought my truck from about 40 miles away (Tustin Dodge). The salesman put me through to the service department. They recalib for free. Why not, I just dropped 40 grand there..... It took all of about 3 or 4 minutes.....
