if you want a fast sedan get a 335i, STi or EVO don't bother with the TSX. its a great commuter car but don't bother trying to make it a race car. waste of moneya $600 chip gets a 335i to 360whp with pretty much full reliability. it would be a ton of money to get a TSX to that level, and reliability would pretty much be out the window at that pointfor what's its worth, i have a '02 wrx which is much easier to mod than a TSX but i am keeping it stock because its just not worth it to mod these days since there is so much fast stuff from the factory. swapped hondas were awesome 6 years ago, but its time to move on
