I have a 2003 2500HD with Duramax and Allison.I've added a 4" Magnaflow exhaust and K&N air filter. It runs great and no problems so far. But all this talk of injector failure in 01/02 models, and that perhaps 03 Duramax might be "down on power" has me wondering. Was the injector problem fixed for 03 models and is the power rating the same for this Duramax as previous years? Any problems out there anyone with 03 Duramax??

Todd -you'll find a lot more info a little further down, in the Duramax etc's, and the 2500-3500 areas. ( not all good, from what I've been reading)

I talked to my dealer service manager recently and he said GM Canada has issued a Vehicle Special Policy for the injector ball seat problem for 01/02 models, and that they've extended the engine warranty on 01/02 Duramax to 7 year or 200,000 miles (320,000 km). Has not heard of problems on 03 models yet, but I assume they would have the same policy for later years if the injector problem persists. Anyone heard anything else??
