For the Cheby's try http://www.62-65-dieselpage.com . I currently own an F350 Powerstroke, but the last two were 6.5L's.

One warning about taking your Ford into the dealer with the reprogrammed ECU - DONT! The new 6.0L Powerstroke has had a dubious debut and Ford is using any excuse to void the warranties. My dealer even went as far as to tell me that just the Banks exhaust would be enough for the warranty to be denied by the factory. It's a no-brainer with a module or re-programmed ECU. Restore the code and drive for a while before taking it in. The ECU maintains an internal audit trail which takes something like 50 Start/Stop cycles to flush out.
