    I'm now dealing on a 2007 Silverado 1-tonner with Duramax. I'll also stay away from tuners, cold-boxes, gee-whizzes and Jim-cracks.

    I just ain't smart enough to outsmart GM's engineers.
    My Jim-crack rocks. Makes my truck go straight uphill and get 30mpg.

    Some of those old 6.2s really hung together. If it went this far, it might go another 250K. You aren't CLUNKING it, are you?
