Tuning with intact warranty

krazynismo

i think it will depend on what you do before you go in for the warranty service.

if you leave the modified parts and the modified tune on your vehicle they will be able to tell.

you may have to change the exhaust, intakes, and tune back to stock.
i think you could flash your ECU back to stock (assuming you have the cable) before the warranty work and drive a set amount of miles so that your ecu doesnt show a previous reset.

i would suggest talking to a professional tuner or shop like Z1 motorsports, or the stillen product support line and see what they say to make sure.
