    I'm considering a tune for my car. I was just wondering how a tune will affect my warranty.

    If you use a handheld tuner like the sct-X4 you can put your ecu back to factory with a few clicks of a button and about 20min of your time.

    It won't affect your warranty at all, as altering the ecu is reversible. However, when ever you take it in for any services other than an oil change, you'll want to put the stock tune back on first. That way the performance tunes won't be blamed for any issues you might be having.
