Even a 430 hp M3 didn't stand a chance. You also need to keep into perspective just because a tuned car is faster, you can't judge performance just by looking at the video's. I pulled so hard on a CLK500 that you couldn't hardly see him in the video when I finished. I would use that as a comparison between a stock 335 and a well tuned FBO 335 with stock turbo's. Now, when you talk upgraded turbo's, whole different game.
So a FBO 335i with stock tune make the same WHP as a Stock 335i? My 08 335i AT in stock form made 274 WHP stock.
