I chipped my 02 TT 225 a few months back and was tuned for 93 octane. When I first got the chip it made a woooooooooosh kind of sound at high rpms when I opened the throttle. Recently the sound went away and don't know if this is common or what. I have always put 93 in my tank since I had the chip.

Thanks Cincy this is my first audi TT and the first mod I have put on the car. I just want to make sure everythings running right because the sound I was so used to disappeared.

if you dont have one, please invest in a boost gauge. It is a great tool to make sure your car is running right and is a cheap expense ($40-60 for a good gauge).
