AEM X-Series Tru-BoostX Boost Controller Gauge Kit, 80 psi - 30-0352

The AEM 30-0352 Tru-BoostX is an electronic boost controller and boost gauge in one 52 mm housing. Its internal sensor reads from -29 inHg of vacuum up to 80 psi of boost.

It replaces a manual boost controller with two programmable boost levels and a scramble setting, all set from the gauge face.

Fitment and requirements

• Turbocharged engines with a wastegate actuator fed by a boost pressure line, so a solenoid can be plumbed in line
• Needs switched 12V power through a 5 amp fuse, a good ground, a pressure line from the intake manifold to the gauge, and a spot to mount the solenoid
• No vehicle-specific harness or brackets; fit depends on your wastegate setup, plumbing and gauge location

What it does

• Boost gauge and electronic boost controller in one housing
• Internal sensor: -29 inHg to 80 psi
• Two boost settings plus a scramble mode
• Set up entirely from the two face buttons; no laptop needed
• Over-boost cut: if pressure stays 10 percent above your alarm setting for more than one second, the gauge shuts the solenoid off, flashes all 24 LEDs and shows Ob until you press a button or cycle power
• Warns if the solenoid is disconnected or shorted
• Sends boost, target and duty data over AEMnet CAN for logging
• Ground output for an optional warning light

What is in the box

• Tru-BoostX gauge
• AEM boost control solenoid
• Wiring and plumbing hardware
• Mounting bracket

Installation and limitations

Plumb the solenoid between the boost source and the wastegate actuator following AEM's port diagram, then run the gauge pressure line to the intake manifold. Start with low boost targets.

The over-boost cut turns the solenoid off, which lets boost fall back toward the wastegate spring setting. It is a safeguard, not a guarantee against engine damage. The controller does not change fueling or timing, so retune for any boost increase.

Frequently asked questions

Does the AEM 30-0352 Tru-BoostX kit include a boost control solenoid?

Yes, the AEM 30-0352 Tru-BoostX kit includes an AEM boost control solenoid. A replacement is sold separately as the AEM boost control solenoid 30-2400.

Does the Tru-BoostX need a laptop to set up?

No. Boost targets, scramble and alarm settings are all set with the buttons on the gauge face.

Do I still need a tune?

Yes. More boost needs matching fuel and timing.
