we just got a new (about 2 weeks old now) 03 2500HD duramax/allison 2 wd truck. anyone know of any boards that have good disucssion on these trucks? i know of www.pickuptrucks.com and www.thedieselpage.com but that is about it and both are pretty slow on diesel talk. there are a few real big cummins sites but that is of no value to me. already have one mod on there and dynoed over 730 rwtq on this tow rig and looking for some easy stuff.
