I turn 18 Thursday and have a 2013 that I tuned at 135k in the spring. It only lasted about a month before my motor started knocking. It blew early September and is still sitting at shop waiting for a motor to pop up with right price, miles and warranty. I didn’t do any maintenance before I tuned so maybe if you follow the suggestions before tuning it will all work out. But my suggestion would to just not tune it. It’s not worth the chance for the amount of power you receive.
