Stock tune for Suburban 1500 LTZ vin3?

[brantmcgee]

I purchased an i3 to disable the AFM in my Suburban. I broke the screen on thei3 tuner and returned it for service. Came back without the stock tune so I cannot load any more tunes. Stealerships won't touch it around here after I altered the stock tune. Where can I find a stock tune for a 2011 suburban 1500 ltz vin 3 so that I can get it back on the tuner? Thanks!
