It's extremely simple..the default button for a 360 controller to use nitrous is "B". Try reading the instruction manual that comes with the game next time instead of posting a topic like this.
sjgphotoDOTcom posted...He may have rented the game and didn't come with a manual. I know gamefly doesn't include manuals with the rentals..
No offense, but that's no excuse. It sucks, but that doesn't matter. Basically every game has in-game controller setup. They could have looked into that first instead of posting a topic about it.
