My biggest worry when waiting for my reserved Si was the power numbers and the 5hp loss everyone was focusing on but my car actually feels quick and more than 200hp. The only tune I would even remotely consider would be to just eliminate the rev hang but other than that it's actually faster than I expected. I did see that dyno video of an Si making more power than what Honda claims but what do you guys think? Also, mine seems to be very well built, no rattles or weird noises, everything is straight as an arrow and solid. It's unfortunate people are having build quality issues but I'm in love with this car.
