I'm guessing, just from what I've read on other forums for the past five years or so, that any tune is going to void the warranty and yes - they'll probably find you've had one. Warranty repairs are a major expense for auto makers and all of them are taking steps to ensure they only make those that are legitimate. In case you haven't heard, GM vehicles from 2018 and up have encrypted operating systems and are nearly impossible to modify. GM makes an exception for Corvette and Camaro because they want those buyers to be able to play with their cars. I chose the raptor because it can be tuned when and if I decide to do so.
If you decide to make mods, then you should assume that the warranty is gone. Then you won't be disappointed if the service manage tells you that your warranty has been voided.
