Can the Iintune programmer turn off the O2 sensors in my 09 Chev Suburban? I plan to install long tube headers with an off road y pipe and expect this to throw the check engine light.

no.. you need to get a custom tune done for that... which you'd want to do anyway with adding headers, since there's other things like fueling that you should get adjusted anyway...
