In addition, Turbosmart's E Boost Street features an over boost shut down protection function where if the max boost setting is surpassed boost will automatically be cut to protect the engine.  Lastly, a programmable boost correction factor can be set using the E Boost Street. This feature allows a tuner to combat boost drop at high RPM which results from a build-up of exhaust back pressure.  By ramping up the solenoid's duty cycle, the power band can typically be extended by another 1,000 RPM.
