Has anyone had warranty issues with the dealership after replacing the aftermarket cai with the stock airbox and reflashing from a custom to stock tune??

 

Haven't tried it yet but would like to hear replies on this also. Thinking about doing custom tune on '07 ROUSH and I've already been told by dealer that they're tempermental on mods.

 

Again and again, the dealer would have to prove that your mod caused whatever the warranty work is that they won't cover. Get over the dealership and their reaction to what you do to YOUR vehicle. I've taken my car in and never reverted back to stock. The dealer's personnelnever blinked other than commenting how nice the Stingers sound.
