Top 11 Best Electronic Boost Controller Review & Buying Guide [2021]

An electronic boost controller uses a solenoid or a stepper motor to control the air pressure presented to the wastegate actuator. So simply put, the boost controller monitors the amount of boost pressure received by the engine, reducing, increasing, and directing the excess to the wastegate.

For you to get optimum performance, for your turbo engine to remain in good shape, and to avoid frequent trips to the auto parts store, your air and fuel mix in your turbo engine must be just right.

When a turbo engine runs too rich, it signifies a high concentration of fuel to air. The result of running rich is that you burn more gas/diesel while reducing engine performance.

On the other hand, excessive boost (also called running lean) means a higher ratio of air to fuel in your engine.

Running lean is dangerous and results in burnt valves, damaged pistons, a jerking motion when you drive, and a car that no longer runs.

When you add an Electronic Boost Controller to your engine, you get the optimum boost pressure which produces extra power and saves your engine from damage caused by running lean or rich.

If you want to know more about the best electronic boost controller for your engine, you should read further.

We will look at the features of some Electronic Boost Controllers in the market and their pros and cons.

Best Electronic Boost Controller: Buying Factors

An electronic boost controller helps you extract as much power from your turbocharged system while keeping your Air/Fuel Ratio and Oil pressure stable and protecting your engine.

When the turbo engine receives a boost in the intake manifold, it stores it until it reaches a predetermined pressure which causes the wastegate to open and release the excess producing more power.

Electronic boost controller’s mechanisms work thus: they delay the signal from opening the wastegate at the factory predetermined pressure point, letting it stay in the intake manifold for longer and increasing the pressure thus creating more boost.

Hence by restricting the amount of boost the intake manifold holds, it lets you control the boost.

There are two things the Electronic Boost Controller can use to alter this signal, a stepping motor or solenoids.

While solenoids act as an electronic control switch, stepping motors monitor the pressure and adjust or balance it.

There is always the risk of using the wrong Electronic Boost Controller for your engine.

Always do your due diligence on the different types of controllers in the market before you purchase one.

These are a few other things you should consider before you buy an electronic boost controller:

Type of Boost Controller

Bleed Boost Controllers

These boost controllers are commonly installed on the wastegate vacuum line.

These give up a small boost pressure per time by bleeding some pressure from the vacuum line, which will cause the turbo engine to release even more pressure, ultimately resulting in a boost and producing extra power to the engine.

Electric Boost Controllers

We have said a lot about electronic boost controllers in the rest of this article.

They do have a slight edge over the manual boost controllers because of the ability you get to monitor your boost from the comfort of your cabin, increase, preset, and adjust to your preference.

Like we said, check out the AEM UEGO Turbo Boost 3 Gauge Combo Set as to how it fits in with your engine. We believe it is the Best Electronic Boost Controller in the market today.

Manual Boost Controllers

These are very simple, cheap, and easy to install substitutes. However, they can only provide one level of turbo boost and do not provide any Air/Fuel Ratio Gauge, PressureGauge, etc.

Also, you can only set the boost level by manually manipulating the knob until you think you are satisfied.

It might not be the best way to protect your engine since you cannot monitor the numbers to detect any problems.

And if issues do arise, there are no fail-safe methods like warning lights or alarms to indicate.

However, if you want the simplicity and reliability of a boost controller without any extra features, the manual boost controller is the way to go.

Ease of Installation

When buying a boost controller, it is wise to search for Boost Controllers that are easy to install and use.

Because they are electronic, they need more technical work than the manual boost controllers.

To ensure that all precaution is taken, it will be wise to get it professionally installed to avoid engine troubles.

Ease of Use

Buying an aesthetically pleasing boost control unit is one thing, but ease of use is another important thing.

Little things like auto-dimming backlights, interchangeable faceplate and bezel colors, overboost warnings, and clear OLED screens make each unit not only beautiful but easy to use.

Another important thing is the placement of your boost controller.

Placement of the boost unit is important so that in driving situations, the numbers are in view, and the driver can monitor it without turning his head.

Kit and Installation

Electronic Boost Controllers usually come in a kit with everything you need to install them.

If you’re a newbie, it is advisable to get one that comes with a kit to ensure you don’t have to start another search for the correct wires, vacuum caps, etc.

FAQ’s of Best Boost Controllers

Why do I need an Electronic Boost Controller?

If you have a turbocharger and you want even more speed, you need a boost controller. Your regular turbocharger engine repurposes its exhaust gas.

It pushes this gas into the turbine, rotating it and increasing the horsepower(hp) of your car.

Depending on the health of your engine, the turbocharger can send more boost to the engine than is required, damaging to the engine.

When an electronic boost controller is installed correctly, it sends a message to the actuator of the diaphragm-like wastegate to open when the preset boost limit is reached.

A boost controller intercepts the message before it gets to the wastegate, giving the engine more boost and letting the boost pressure out at the right time to decrease the boost and protect the engine.

With a boost controller, one can preset and monitor boost from gauges inside the car for a better driving experience.

Boost controllers nowadays have alarm systems to warn and shut down the engine if ever needed.

On what type of engines can I install the Electronic Boost Controller?

One can install an electronic boost controller on any turbocharged engine.

Can I install the Electronic Boost Controller without professional help?

Self-installation of an electronic boost controller depends on three factors;

  • The type of boost controller

Some boost controllers are easier to install than others. You can check the list above to see which ones fit your engine

  • The engine

Every engine looks different, sits different, and houses components differently. Always do some research on your engine before you go ahead to do any installation.

  • The technical expertise of the driver

If the instruction booklet is not well outlined and you cannot find a video that details the steps, it will be wise to contract a tuner or a professional installer to avoid damaging your turbo engine.

Is the electronic boost controller safe for my engine?

Any post factory enhancement on your vehicle has the potential to cause issues to it. However, with proper care, the boost controller will help you protect your engine.

For your Electronic Boost Controller to work optimally, it needs to be installed properly. Improper installation can damage your engine.

After installation, the boost controller needs to be tuned and set up correctly or it can damage your engine.

Does the Electronic Boost Controller come with an installation manual?

Most EBC kits come with an instruction manual.

How do I choose the Best Electronic Boost Controller for my car?

You should choose the boost controller that is effective for your needs. It should be easy to install and durable. It should be easy to read, producing low latency and feeding real-time results.

And when you run your electronic boost controller on your engine, you should be sure you increase the boost levels only a little at a time, nothing more than 20%, to protect your engine.

Of course, you should never increase your boost higher than your mechanical Air/Flow system can handle.

Why should I pick an Electronic Boost Controller over a Manual Boost Controller?

An Electronic Boost Controller allows you to regulate your boost from inside your car, while with the manual boost controller, you only control the boost from under the hood.

With the Electronic Boost Controller, you can regulate the amount of boost you want and adjust it as you drive, but with the Manual Boost Controller, the boost level is constant as the knob is on the device under the hood.

While the manual boost controller might be perfect for daily drivers, the electronic boost controller is the right choice for functionality, performance, and style in street and track racing.

Manual Boost Controllers are cheaper and easier to install. Electronic Boost Controllers are expensive and difficult to install.

However, installation difficulty is compensated for in the different settings and modes available on the EBC.

What steps do I need to follow to install my Electronic Boost Controller?
