Get more performance out of your electronically controlled engine by plugging in one of BDs Electronic Boost Builders. Installed in-line with the MAP sensor, the Electronic Boost Builder increases boost pressure and intercepts the message to the ECM, preventing it from setting an over boost trouble code that can cost between 50-80 horsepower. BDs Boost Builders are a perfect match for engines with non-boost control power module, injector or turbo enhancements.
