Ebay.com has chips for all cars, up to 25 more horsepower. Just type "performance chips" and click search.
i'm sorry but i wouldn't go for an ebay chip. they may seem like a great deal cause their only $25 but they are not made by reputable companies and don't offer dyno tested horsepower figures. spring about $300-$400 and get an APR chip. they make chips specifically for the 1.8t engine and can give you and increase of nearly 40 horsepower.
I have a better idea. I have a 1998 and i didnt want to go ebay but 300 is too much. If you go to www.horsepowerfreaks.com they have the neuspeed p-chip for 184.00$
if your car is turbo then go to www.goapr.com.au and they can sort u out. best perforamce for audi and vw
