. Hopefully I won't ever have to find out. I have been to every dealer in my area (for the clunk on decel in the lower gears, especially when towing on an incline or in stop and go) and they all mentioned my ESP warranty in some way with remarks like "no matter what you're covered". This is after a self-installed level lift, bigger tires, and the tune, so I feel pretty reassured. I am aware however that because of the tune they can make whatever choice they want. YMMV.
