Please consider starting a 6.7 forum as the C & C truck is currently on the streets with the 6.7, and everything else except the 4500 and 5500 will be on the street after 1 January07. TDR has just put one up, and its been suggested at DTR. Good info on the 4500 and 5500 at TDR. Likewise for the Ford guys with the 6.4. Dave
