Introducing the new Greddy Profec controller! The large OLED display with its simple two-button / rotary-dial control makes for easy operation. The ultra slim controller can display boost in digital, bar-graph, or graphical modes and can be rotated 180 degree for installation. Installation is easy and 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 3 port solenoid valve, and the faster ECU processor all provide quicker response and the most stable boost curves yet.
