Hi everybody,
I have a 2011 GMC Sierra 1500 4x4 that I am about to start a DOD delete on. I hope to use Tunerpro to disable the DOD in ECM. I may also delete VVT but have not decided for sure yet. Hopefully I can find the files I need to do this.

Welcome.

You will need an .xdf(OS Specific) and a raw .bin to make use of TunerPro. If you do not have both, you will need to acquire them along with any necesary hardware to flash the modified .bin.

Thanks buddrow,
I am still reading all I can on the subject and looking for the files I need. I removed the valve covers yesterday and found #6 intake lifter is compressed and the rocker has a big gap. That explains the knock that the engine has.
