I am just looking for imput from other TT owners...... I have a 2001 TT Quattro and am beginning to "spruce it up a little". I am adding a K&N breather next week and have plans to upgrade the susupension and possibly a computer chip. I know little about the chips other than a price range of $69-800. What are the best ones, and why so much difference in price? Is the price reflective of quality and performance? It is like water skis, you don't really know until you spend the money and try one? Any ideas on places to install a suspension upgrade? Have any others have this done? My suspension works fine but is squeaky. I would rather upgrade than replace with stock parts. The cost would probably be close. This is my first day as a member. This looks like a great site.
