    How ever long the car runs.
    Tune isn't a need after LT's. Just something that would maximize the mod.

    I got all my mods done first before I got it tuned. The car ran fine but not nearly as well as it could.

    GM pcms have a beautifull thing called fuel trim: This is a correction factor between what the MAF sensor says is necessary and the actual oxygen level at the O2 sensors, the headers will cause a shift in the efficiency of the motor but with the exception of first start up , the pcm will over timecorrect any(within reason) deviation. I have gone as far as to leave a large vacuum line off and watched the fuel trims correct up to %50 and had a vehicle still run reasonably well.
    It wont run perfect mindyou but you wont damage anything.
