I definitely recommend adjusting your 2022 GMC Sierra 3500 back to the factory settings and then potentially removing the Edge Pulsar V3 L5P Inline Tuner # EP82AR prior to taking it in to a dealer for service. I'm not sure if it will do anything to the warranty but dealers aren't the biggest fans of tuners so it's best to go back to the OE settings and remove the tuner in my opinion.

As far as the warranty goes you are protected under the Federal Magnuson-Moss Warranty Act. The Act states that if something breaks on your vehicle and you take it in for warranty repair, the dealer must honor your warranty unless whatever modifications you have added to your vehicle actually caused the problem in question. So unless your warranty specifically states something about not using a tuner it "should" be fine but it will be a lot easier to just restore the settings to factory and remove the tuner than to fight with your dealership about it.
