The new PRofec is compact, powerful and easy to use. The large OLED Display, with the simple two-button / rotary-dial control, make for intuitive operation. An ultra slim controller can display in digital, bar-graph, or graphical modes and can be rotated 180 degree for installation with the included adjustable mount or flush mounted. By separating the display and control unit in the driver’s compartment, from the engine compartment-mounted, waterproof, sensor unit, it makes installation straightforward. Only one thin harness is required to be routed through the firewall. The combination of the new 300kPa (43.5psi) integrated pressure sensor, the more compact solenoid valve and faster ECU processer, provide quicker response and the most stable boost curves yet. The PRofec also maintains popular features like, Lo, Hi, Scramble boost presets, last-boost display, peak-hold recall, warning alert and safety limiter. The next evolution of the GReddy PRofec line of electronic boost controllers is here!

Separating the Display Unit from the Sensor Unit


To keep the Display Unit as slim as possible, a separate water-resistant Sensor Unit was developed. The added benifit of this however, is the convenience of installation. Now that the Sensor Unit is mounted in the engine room, only a single thin harness is required to be routed through the vehicle's fire-wall.

Select between 3 Types of Boost Display Screens
(kPa or PSI)

 Numerical Display

 Bar Graph Display

 Map Trace Display


* Programable LO and HI Boost Pre-Sets, with a 3rd Scamble Setting

 Timed Over-Take Boost Level

* Intergrated 300kPa (43.5psi) high-performance boost pressure sensor (within the Sensor Unit)

* The PRofec can display the last (peak) boost value after each boost session

* The Peak-Hold Function can display the maximum boost recorded

* Boost levels and stabilty can be fine-tuned by adjusting the GAIN and START BOOST settings

 Warning Feature displays an visual and audio alert when the unit detects an over-boost situation

 If the boost warning level is surpassed, the PRofec can reduce boost levels via a programable Limiter Function
