Based on the very popular B-Spec., the all new PRofec B-Spec. II's basic function to increase boost is as easy as the original, with an added built in boost pressure display and optional features like real-time, peak or last boost display (in either kPa or PSI). There are optional warning and boost limiter functions that can be programmed to offer much more control. The two presets values can be stored and are executed by a larger capacity inline solenoid valve. This unit does not require extensive programming and is ideal for low to high boost levels for single or twin turbos with actuator or external wastegates. The GReddy PRofec B-Spec. II is available in black or silver cased head units.
