I do not think each 10k is overkill, but I am good with sticking to every 40k miles. I have another coming up at 160k miles, 6k miles from now. I have a K04 upgrade with GIAC K04 H.O. & DSG tunes. 350 HP and 363 lb*ft, and never had any DSG issues to date...and I have done a good number of 1/4 mile pulls, plus the road miles.
