my car is a2000 A4 1.8T quattro.I am new to this car and dont know much about turbos. What i can say is my car has been lacking the power it had. I did need a new clutch and i replacedit recently.But the car still doesnt have that same pull it had when i first got it. I can hear my turbo working but not much feeling to it. IS there anything i should check first?

first thing to check is the search function at the top of the page,
second i would check for vacuum leaks, are you throwing any codes?
also if you havent done so i would hook up a boost guage and see what you boosting at, it is possible you just got use to the stock 9 psi,
good luck and keep us posted.
