Keep posting your videos, I for one love them and it gives me a comparison with how my car behaves. I have the same on the gas off corner problem. Since the beginning. My solution was playing with toe in. I feel the same way about the wavetrac. Sometimes I wonder if it's working at all. When new I could feel it pulsing. If you haven't done it already you might try is changing the gear oil. I have a 75w 90 now but it worked better for me with a 75w140. I'll be going back with the next change.
