Tuning paremeters?

    What paremeters work for you with the 5.3? Any suggestions? For now, 2010 Sierra Crew Cab w/3:08's and running 87 octane, pure stock under the hood. I have a SCT tuner but Diablo T1000 may be in the works.

    With that type of tuner you really can't damage too much, because they have safety limits on it so that you don't mess anything up. Now when I bought HP Tuners and started tuning my 5.7, there are NO safety's and you CAN screw a lot up. I don't know how many times I flooded the motor, and fouled the plugs until I finally just had it professionally tuned....

    The t1000 is an awesome tool for sure!
