Probably not high boost that causes his plugs to foul... its lack of fuel. Turn the boost down or get more fuel. Simple fix. Boost controler and gauge and you can see and control the boost level.. then its just fuel.

Plugs dont just foul from high boost. If the plugs are white then you are not getting enough fuel for that amount of boost. If they are black, then you are getting too much fuel. By saying they foul with"high boost" I would guess the plugs are white and he is killing them with detonation.... not to mention the rest of the motor.

Maybe some full sentences with mods to the car and boost level would help, but thats my shot in the dark.

100% need more details in the setup.

If the plugs are black, it might also be because he's running too cold of a plug.
