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