Hello fellow duramaxers. Been lurking on this site for awhile now. Its been a great wealth of info as I researched my first diesel purchase. Bought a nice 06 LBZ CC/SB SLT with dual exhaust, s&b intake, and it already had tunes by Idaho rob. Very happy so far as it gets as good or better mileage than our minivan and I love the power. Glad to be a member here and look forward to learning a lot more about these trucks.
