    Not a factory tune yet. Would really love to find one to compare it to the truck version. Shouldn't be that different but I feel some slight surging at mid throttle with the truck tune. Also a little soggy when pressed hard. Light throttle feels pretty good except under heavy load.

    The tune that I had attached to post #10, was a stock 2007 Suburban L76 calibration - modified for your vehicle (which was originally equipped with a 5.3L Flex Fuel engine).

    I haven't tried it yet but if you have a stock tune for an 07 Suburban, that's what I need. There is nothing left on the 'burb from the 5.3 flex fuel. Everything from radiator to fuel pump intake to oil pan IS L76.
