First off I was wondering how much horse power a '02 225 tt quattro would get to the wheels?
Also I was curious on what parts are needed to classify it as stage 2 and how much power would you be getting then compared to stock?

So far I found that vagtech said that a mk1 tt would need to be chipped, have an upgraded diverter valve, performance air filter, and a turbo back system to be classified as stage 2.

 

not sure about what the whp would be but stages usually depend on what software u go with, i know unitronics for instance stage 2 recommends an upgraded intercooler i believe

 

Where is murderface with his rant on stages. Stages mean nothing cause they mean different things to different people. What you listed will be around 230fwhp or 200awhp depending on how you dyno. However tq should be in the 265 range.

A little research goes a long way. Like cincy was implying, "stages" are a software manufacturers recommendation of modifications to have. Doesn't necessarily mean you need to have those but for the optimal result of that software, they would be ideal.
