[007Classic]

Hello Everyone,
I just joined this forum and just purchased my first duramax turbo diesel vehicle. I bought a 2007 Classic and do not really know where to start. I have many questions for all of you. I want to tune it but do not want to void the remaining warranty or damage the vehicle. Any advice you can offer would be a great help.
I look forward to learning about this truck with your help.
Take care

Lots of great info here, you will find this is a fairly performance orientated site.
There isnt really much you can do that wont void the warranty...
How many miles on your truck?

Thanks, I have 33K miles at this time. I am looking to get more fuel mileage out of it mainly. Have you or anyone else heard of the tuner from http://www.powerupdiesel.biz? They claim to have a stock tune to revert back to if it needs to go back to the dealer. It seems as if the truck had MUCH more power and I know the fuel mileage was better before the dealer replace the turbo recently under warranty. Any thoughts? I had a check engine light come on after buying it. I found this forum looking the code up, P003A I believe it was.
