Warranty?
how much they want to beat you out of claims. Me,
when I was taking it to the dealership I always put
back the stock tune. Now it's modded past the point
of being warranty-able and I don't go to the dealer
anymore anyway.
But I'd keep the stock tune handy if you were going
to try and, say, get a new transmission for free. The
dealership might be clueless about tuning but why
bet?
Especially if there are any other modifications on the car that would tip off the dealer that you are a tinkerer.
Any indication of defeating failsafes like torque management means your claim is toast.
