Just a little update...
Turns out, my truck is one of a handful that would not tune with the MM3 unless I returned it back to stock.
Minor setback, but once I did that, the MM3 worked flawlessly.

I also went from the H&S to the DRD MM3. I would recommend you go back to stock with the H&S. The main reason is that once you do that, the H&S is not VIN locked to your truck.
That way you can put it up on EBAY and make back a little money.
If you Tune over the H&S with the MM3, your H&S will be VIN locked and can never be used on another truck
That is exactly what I am doing. Fortunately the mm3 would not program without me returning to stock.
