Game Description:In Import Tuner Challenge, the speeds you reach as you take on the world of underground Tokyo street racing are impressive. But the game's most eye-popping number? Five million. That's the number of customizations you can make on the licensed import sports cars you have at your disposal. Make almost any performance or appearance mod you can imagine with authentic parts from real-life manufacturers like Mazdaspeed, C-West, and more. While you may leave your opponents choking on exhaust, you'll be hard-pressed to exhaust all your possible opponents. The game features over 400 unique opponents. Race them on re-creations of real-world Tokyo highways, or go head-to-head with friends via Xbox Live.
