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.

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.

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!
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.
