Extra Info: Includes printed tuning and fitting instructions and everything as seen in pics which includes a couple of metres of vacumm hose from AVO Turboworld (never used).

Great boost controller for anything under and including 18 psi, held rock solid pressure despite the poor dump pipe design of my turbo back exhaust system on my wrx. Fixed spikes and hesitation problems. Great warning and safety features.

This unit features a built-in boost gauge, peak boost display, four different boost settings, boost warning, scramble boost, and a boost limiter safety feature to prevent over boosting.
The DSBC Spec S uses a single solenoid design for better boost response. The DSBC Spec S is 1/4 din in size and is compatible with internal actuators and external wastegates.

This unit is available in a silver case with an green LCD display. The difference between the DSBC Spec R and Spec S is the solenoid design. Spec R uses dual solenoid while the Spec S uses a single solenoid design.
