This aluminum-alloy boost controller lets you fine-tune boost pressure without replacing factory components. Designed as a universal inline solution, the kit includes the controller and installation accessories to connect into a turbine vacuum line using the supplied 4AN-to-1/4" hose fittings. It’s made to be durable, corrosion-resistant, and easy to install for hobbyists and professional mechanics alike.
The device intercepts the turbine vacuum line and modulates actuator pressure via an adjustable screw, raising or lowering boost relative to the wastegate set point. Adjustments are mechanical and immediate, letting you dial in the desired boost level within the 1–30 PSI range.
Installation requires cutting the turbine vacuum hose and installing the supplied tee, then connecting the controller between the lines and sealing all connections. No vehicle-specific modifications are required, though basic hand tools and a few minutes of mechanical experience make the process faster.
The controller is built as a universal inline unit intended for a wide range of turbo engines; compatibility hinges on having a compatible turbine vacuum hose and typical wastegate plumbing. The housing is fashioned from aluminum alloy to resist rust and wear under underhood conditions.
Who is this for: The Caoeal Manual Boost Controller Kit is aimed at car owners, tuners, and mechanics seeking a straightforward, mechanical way to alter turbo boost without electronic controllers or major modifications. It’s suitable for enthusiasts who want hands-on control of boost behavior, garages fitting customer cars, and anyone wanting a compact, durable boost adjustment solution for a turbocharged vehicle.
Q: What boost range can I set with this controller?
A: The Caoeal manual controller is adjustable from roughly 1 PSI up to 30 PSI, depending on your turbo system and tuning.
Q: Is vehicle-specific wiring or tuning required?
A: No electrical wiring is needed; installation is mechanical. ECU or fuel tuning may be advisable if you change boost significantly.
