GReddy Profec Spec II electronic boost controller
The last power related modifiction done before the ECU replacment was to fit an electronic boost controller.
Got a second hand GReddy Profec Spec II electronic boost controller and positioned the unit under the dash where it
is out of the way but still visible. After downloading a user manual for the unit I set it up for 0.7 bar which
is the same as the maximum boost the stock boost solenoid goes to.
