Wait? Are you saying that I think Sofa King doesn't have "morals" and I prefer GDE? Then you are WAY off base. My comment wasn't directed at neither company. In fact, I don't have an opinion on either as I've not used either personally.
It's the moral aspect... if you modify the write counter to help the consumer and in turn not void the manufactures warranty, what does that say about your company?
And yes, the dealer can't likely tell if the truck has been tuned, but I promise you the engineers that developed the factory...
Welcome!
I'll let the guys chime in here on some questions you have.... as far as warranty, tuning it will likely void it IF something happen. But, the increase in power is nice.

But, you'd have to put the truck back to stock to get the payment. Can't put the AEM tune on the truck with no DPF..
Welcome! I would ask what tuning they are using, as most diesel shops just resell big name tuning out there and their upcharge. Usually tuning should be about the same price, and you're just paying the labor for the install + hard parts.
