Hi mikel
In fact, I wait for you to answer ... my experience in the auto tuning is very simple, any way ... yes this with the stock tune ...
Thanks

what you are hearing is the slip yoke on your transmission, its really common with these trucks. I had the same thing with my truck.

yeah, that's a mechanical problem with your truck, not a tuning issue...
