The Electronic Fuel Regulator allows higher boost pressures while maintaining the factory fuel pressures. This is essential when doing any turbo modifications. When the turbo produces boost pressure over stock, the engine will then reduce fuel. The Boost Fooler will allow you to get the extra boost out of your turbo with avoiding the factory defuel settings.
