How to Turn Up a Stock Audi TT Boost
The Audi TT is a luxury sports car that uses an inline four cylinder engine. The engine is turbo charged and makes about 200 horsepower. The Audi TT is a light vehicle, so 200 horsepower is more than enough to hit the street or track. However, you can manually turn up the Audi TT's turbo boost using a boost controller.
