"Customer damaged engine due to now removed aftermarket parts but previously documented"
Auto warranties are regulated by the government, why would you ask a dealership who has no control except to attempt to void your warranty with the Manufacturer not the dealership?
You may as well call up the FTC and ask them instead, at least at that point you don't get yourself put on a list.
If you do something to damage your truck expect to pay for it, that includes putting mods on.
Properly changing the tune on your truck, or most in-line modules like the Pulsar will not make the truck preform out of spec, ie try to change gears at 9100 RPMs so it's not going to cause any damage.
The Magnuson Moss Warranty Act (MMWA) prevents manufacturers from using disclaimers on warranties in an unfair or misleading manner.

The Magnuson-Moss Warranty Act prohibits product manufacturers from conditioning consumer warranties on the use of any original equipment part or service. Furthermore,
a manufacturer can only deny warranty coverage if it can demonstrate that a non-original equipment part or related service caused a defect to occur in the original product.
