honestly i brought mine to the dealership to get the 5k service and they didnt ask me anything about a chip. i actually talked to a dealer inside later and he said that sometimes they will ask you to sign a paper asking if they can re-flash yer ECU but if you have a chip you are allowed to say no... so really yer warranty is voided if they suspect a chip or they are pretty sure you have one. the only way it will void it is if something breaks because of it (like the turbo).
