All depends on dealer, what mod, and most important, how much $$$$$$$$.
Yup.....and when you do hi-po mods yourself, all bets are off. All work must be documented by the factory if they are going to foot a bill for major mechanical work......shadetree mechanics with these high tech ECU's today is taking a huge financial risk. A friend of mine, who is a Master Mechanic for Ford told me last week, the biggest red flag for warranty denial today is the aftermarket tuners......enough said.
