Import Tuner Challenge[a] is a racing game published by Ubisoft and developed by Genki for the Xbox 360.

After the 13 Devils have been defeated once more in the Kaido Circuit, Motoya Iwasaki, aka Speed King, disappeared suddenly, leaving without a trace.

The hero here is the best friend of Iwasaki and beats Bloodhound, Midnight Cinderella, Platinium Prince, Skull Bullet's gang & eventually, the Phantom 9.

While the Japanese release of the game was well-received by Famitsu,[citation needed] it garnered mixed to negative reception from Western publications.

[2] TeamXbox's Nate Ahearn rated the game 4.9 out of 10, saying, "Tuning the numerous parts of your car provides for some decent variation, but you’ll soon figure out that the actual gameplay just isn't very good.
