I got a new intake installed that has carbon fiber over its carbon fiber, and coated my engine in ... carbon fiber.
I also found out that my car was built on a Thursday while there was a big party in the factory in Germany. Apparently, this party included hookers and blow, effectively making my car faster as a result of it.
Based on the above, I've concluded that my car is even faster than I once thought it was.
Proof: I did race a "bi-Bugatti" this morning, which is essentially two Bugatti's strapped together, facing towards the same direction... even with the combined hp, they were no match for my GTI....
