Are any of guys doing the AA tune still with your CPO and maintenance warranties? I got 2 years left, I'm in between ESS and AA bcuz I don't want the dealer to find out that I did a tune then void whatever warranties *I know they won't find out unless they really look but the service guy driving the car might notice* Just wanted a little chime in.

ESS is my first choice cuz I can switch it back and forth on the fly but at the cost it's ehhh but AA one time deal. What do I do?
