Either it's defected or the controller that came with the game doesn't contain the right batteries or microchips.
The boost controller is a device in a car which modifies the pressure reaching the wastegate actuator. The boost controller may be manual or electronic and the effect is to increase the energy of the car.
Check the batteries to see if they are full of power.
Get a manual boost controller ...
The controller that came with the xbox 360 wont, but if you buy a microsft xbox 360 then that works on PC
Best way is to use a BOOST CONTROLLER
Check the batteries. Also check that it is synced to your xbox
In most cases you use some type of manual boost controller between the waste-gate and a good boost source. Or you can use some type of electronic boost controller but this can be expensive.
Is it a wired controller? Is it possible that there's a short in the wire. Wiggle the wire around a bit. At any point does the controller work again (even briefly)? If so, there's a short and the controller needs to be replaced. If it's a wireless controller, make sure the batteries are fresh. If so, there could be a signal problem.

yes all you need is a boost controller
Easiest way is to get a Manual Boost controller. Something like a GFB MBC (Manual Boost controller) is a very easy way to raise the boost. (Google GFB) A Boost gauge is also mandatory if you raise the boost...otherwise you might turn it up to much and destroy the engine!
