GReddy is proud to introduce the next evolution in the GReddy PRofec line of electronic boost controllers. The new PRofec is compact, powerful and easy to use. The large OLED Display, with a 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.
Greddy Profec Oled White Version
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 routedthrough the firewall. The combination of the new 300kPa (43.5psi) integrated pressure sensor, the more compactsolenoid valve and faster CPU 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.

Profec Programing Basics
The Profec is programed with the same 3, easy adjustments as the previous PRofec B-spec2 (SET, GAIN, & START), but refines the programing to one simplified screen, for simple intuitive control. (While the PEAK recall in the programing screen helps the programer see what boost level was.)
SET % = Controls the target boost level. As simple as a manual boost controller. As you increase this percentage from 0-100% it increase boost over factory wastegate spring boost level.
GAIN % = Controls the Wastegate response (stability) at higher RPMs. So if the boost level tends to drop as the RPM rises, you can set the GAIN % to a higher positive value (0 to 100) And if you want the boost to drop at higher RPMs you can set the GAIN % to a more negative valve (0 to -99.
START (Boost) = [CONTROL] Is a boost pressure value that determines Boost Response (or when the boost controller starts to open and close the wastegate.) This is generally set 3-6psi (1-2kPa) below the desired boost level. (if the boost “Spikes” then regains control, it is likely the START valve is too high and should be set lower.) Under the START [NORMAL] setting (if used) the wastegate is allowed to open gradually to the START boost value (more similarly to a manual boost controller. This maybe ideal for more complex sequnetial turbo set-ups.)

Simple rotary-dial and dual push-button layout was designed and developed with an emphasis on simple operation.
Dimensions (89mm X 36.5mm)
- Select between 3 Types of Boost Display Screens
- Programable LO and HI Boost Pre-Sets, with a 3rd Scramble Setting
New Compact Solenoid and Improved CPU Control
The PRofec uses a new more compact 3-port boost solenoid, controlled by a faster CPU. The result is a quicker responding system, that provides our most stable boost curves yet.
Excellent Visibility with the OLED Display
OLED (Organic Light-Emitting Diode) display offers excellent visibility at a wider range of angles. It is also much brighter then standard LCD screens, allowing the display to be more compact, yet still effective.
Slim Design Offers Multiple Mounting Options (89mm X 36.5mm – 11mm thick flat-screen)
Surface mounting, as well as, the rotating of the display by 180 degrees, opens up numerous mounting options. An adjustable mounting bracket is also included.
