The Painless Performance Striker MD intercepts the fuel and boost-pressure electronic signals and allows you to apply infinite multipliers to them for power gains or enhanced fuel economy. You can use the 10 preset multipliers or create your own custom settings for familiar payloads or road conditions. When you add other performance hardware like custom exhaust or a bigger turbo or fuel pumps, the MD can maximize their output.
