    AEM's Tru-Boost Gauge-Type Controller is an electronic boost controller that combines the simplicity of a manual boost controller with the added ease of adjusting boost levels through a gauge interface. There is no external interface required for set up, and it is fully functional right out of the box. There are no gimmicks or special software programs included. If you want more boost press the button on the right of the gauge face, and if you want less boost press the button on the left of the gauge face. It's that simple, and IT WORKS!

    The controller includes everything you need, including an on-board 29 psig pressure sensor, built-in Overboost protection with two timed shutdown levels, a scramble boost setting and a low-side output for a warning light. The boost control solenoid (included) is the only one specifically manufactured for automotive boost applications, which means it won?t corrode and stick from exposure to rich fuel mixtures, it is pressure tested to 100 psi and includes -4 AN fittings to eliminate any chance of leaks.


  • Complete system includes harness, boost hose, on-board 29 psig pressure sensor, boost solenoid, gauge display and all necessary fittings.
  • No external interface required for programming!
  • Two user selectable boost settings with peak boost memory.
  • Scramble boost setting allows user to momentarily change boost levels.
  • User selectable Overboost alarm includes two timed shutdown levels at 10% and 20% Overboost.
  • User configurable gauge includes 24 scalable LEDs, and interchangeable bezel, pin guide and faceplate to customize look of display.
  • One (1) low-side output included for warning lights.
  • Quick connect technology eases the installation process.

    aem true boost

    Very simple boost controller. minimum ability to fine tune. easy installation, clear instructions. came with everything needed for installation. from my personal experience the boost controller was not able to hold peak boost with my 1990 supra but this is most likely due to user error/inexperience. boost controller allows 2 setting to be saved and has a view peak boost option. leds and colors are nice. overall good product. :)
