In my 2500, I used an Edge guage. ( edge products ). Not a chip, just a guage. Plugged into ODBC. It gave me real time data about the diesel truck including tranny temp, exhaust gas temp with add on probe and info about turbo and fuel rail performance It also let you read and reset error codes. I really liked mine a lot.
