Hey everyone, im gettin close to buyin my first, duramax diesel. Ive never owned a truck, ive got a jeep currently, but want to move onto something greater, and I think the Duramax is the way to go over all of the diesels. Im going with a 2006 chevy 2500 with the lbz duramax, so if i can get any help or tips with what i should do first that would be great, I deffinatley think im goin to tune it with Efi Live and so far i have a pretty good idea of what the system is but if someone could really claify how the whole systems works it would be helpful. So with being new I thought i should post something and see how everyone does what that do with their machines.
