Hey guys new member here. My name is JD, I'm from east Texas. New to the Duramax family with a recent purchase of an 07 2500HD 2WD, she needs some tlc and I'm currently fighting an "engine power is reduced" every five minutes, engine running or not. Dpf delete and I was told 150 tune but I'm not sure. Other than that I cant get the fuel rail valve out so I will will be pulling rail soon, not looking forward to that. I've been following this forum for a few years now to get information on the best duramax and now that I have one I decided to become a member, I look forward to being a part of the group!
