Thank you, just thank you. Dealerships will prioritize modifications, just as common sense would dictate. Is one likely to have problems from a dealer with larger tires as the mod, or no honk on door lock, absolutely not. Do they qualify ECM tunes VERY differently, in most cases, absolutely yes, and when one goes to arbitration and there is limited knowledge of the ICE on the part of the arbiter, the dealer needs to do very little to put the entire burden of proof on the modifier of the vehicle. That individual just decided not to pursue it farther, making your point. Some people have zero problems with tunes, but one can't make blanket statements, and the simple fact is dealers routinely deny warranty claims based on ECM tunes. Has nothing to do with being scurred (sic), just making informed decisions. I've openly said I have an ECM tune, and I have it on half of my current vehicles, so I'm not against it, I'm just against disseminating opinion as fact when Wrangler fans are indeed not well versed in turbo ECM tunes.So yes, your local dealer may be fine doing warranty service on a car with a tune. But telling people that a dealer has to prove your tune caused the failure in order to deny service simply isn't true. You'll find plenty of people who had coverage denied the moment the tune was found. Whether you want to pursue things legally at that point is up to you.
