Not OP, but the fact that the dealership can (and will) be able to find out you had a tuner installed and essentially deny any and all powertrain warranty claims is what scares me away from it. On the rare chance something does happen, I don't want to have to pay out of pocket for repairs. I have no issue doing it on cheaper/older vehicles, but to me personally blowing the warranty on a $85,000 daily driver isn't something I want to do. The whole reason I bought this truck was because it already has 540hp from the factory.
That and the fact I don't fully trust this powertrain yet enough to play games with it
Nah, everything installed correctly in about an hour. I don't have premium fuel around me and didn't realize that helped pushed the numbers further. Stock is fine for me im old now lol
