I've got 2500 miles on my TT. During hard acceleration today, the Turbo's eeem to be 'whistling' louder. I also noticed a slight interuption/hesitation. (The hesitation occurred after the Turbo's had spooled up, in other words it happened when they are normally delivering a smooth hard 'punch'.)
Anyone have the same thing happen?

Does the 997tt use the Bosch diverter valves? I remember some people changing out the plastic/rubber Bosch valves for metal types on other models.
