Boost Controller Introduction & FAQ

If you’re fortunate enough to have a turbocharged engine, you already have a factory boost controller fitted to your ride.

However, when it comes to tuning, upping the boost and getting the most out of what your turbocharger has to offer will be one of the most beneficial, cost-effective, and convenient ways to unleash your potential power gains.

At the same time, we don’t want to crank the boost up as high as possible, as we can guarantee your turbo and potentially your engine will soon become a ticking time bomb.

For that reason, we use an aftermarket boost controller to provide a specific amount of boost to the engine so that you can enjoy the power gains without needing to worry about the possible fatal consequences.

What does a boost controller do?

The role of a boost controller is to provide adjustable quantities of boost that can reach the turbocharger.

If you were to install a turbo to your engine without any restrictions, then it would most likely boost until the point of no return.

For that reason, you have a wastegate that limits the amount of boost provided to the turbocharger, feeding it the desired quantities when necessary.

A wastegate is typically found in the exhaust housing of your turbocharger, and this allows a controlled quantity of exhaust gases to bypass the turbine, limiting the boost.

You also have a wastegate actuator, which is typically a component mounted to your turbocharger that controls the opening and closing of the wastegate.

As boost pressure is delivered to the actuator via a silicone hose from the compressor outlet, this forms a control loop.

With the pressure rising, the actuator controls the progression of boost provided to the turbocharger via the wastegate.

If you opt for a boost controller, this controls the amount of pressure reaching the wastegate in the first place.

With a boost controller, you’re able to control the boost level produced in the intake manifold by adjusting the air pressure provided to the wastegate actuator.

There are several ways of controlling boost, from a simple manual control valve housed in the engine bay to a fully adjustable in-car digital display, allowing various setups to be selected or adjusted from the comfort of the driver seat.

Manual vs electronic boost controller – What’s best?

If you’re not already aware, then you’ll soon see in our guide that there are both manual and electronic boost controllers.

Pros of a manual boost controller

When it comes to simplicity, it doesn’t get much simpler than a manual boost controller.

You would fit your manual boost controller into the engine bay and use an external in-car boost gauge to achieve the desired boost levels. However, some recent offerings in this guide will also allow for in-car adjustment.

Think of these as a set-and-forget solution, where you choose the boost level you wish to achieve, and close the hood and enjoy your newfound power.

Cons of a manual boost controller

As convenient as manual boost controllers are, they’re often a little too simple and limiting for those looking to get the most out of their setup.

If you’re looking to adjust your boost settings in-car, then an electronic boost controller provides far more features and flexibility on the go.

Installing a manual boost controller

When it comes to manual/mechanical boost controller installation, this is a relatively easy task, as shown in the following video:

Pros of an electronic boost controller

When it comes to the electronic/digital boost controller offerings, it’s an entirely different ballgame.

With the ability to add numerous boost settings, you’re able to tweak and customize your setup from the comfort and convenience of the driver seat.

Most EBC’s feature high and low settings, which allow for low boost operation when cruising around town, with the high boost option when it’s time to shred the tires.

Typically, an EBC will allow for complete customization of the boost curve by allowing you to adjust the spooling rate, maximum pressure, and reaction time of the controller.

Many of the various models of electronic boost controllers on the market also come with a vast array of additional features and customizations, so it’s worth considering which one best suits your specific needs.

Cons of an electronic boost controller

When it comes to installing an electronic boost controller, it’s substantially different from the manual alternative.

Not only is installation complicated and will require some technical knowledge, but if you’re unsure of how to set up the boost controller, you run the risk of damaging your turbocharger or engine.

For that reason, we recommend professional installation by a tuner to ensure maximum power gains and durability.

What Are The Best Boost Controllers?

We hope you now understand how a boost controller works and ready to decide whether a manual or electronic controller will be better suited for your needs.

Let’s take a look at the best boost controllers on the market.

AEM Tru Boost Gauge/Controller Kit

aem tru boost gauge kit

Our comment: If you don’t want to take up too much space on your interior with a separate boost gauge and boost controller, this two-in-one solution could be the perfect solution.

Using the simple two-button design, you’re able to configure all of the settings that you’d typically find within a separate boost gauge within this handy unit.

As far as electronic boost gauges go, installation doesn’t get much simpler than this, and you won’t have to worry about installing the individual units.

With this kit, you’ll also get a black or silver surrounding bezel to customize the gauge to match your interior.

BluVantage Bluetooth Boost Controller

bluevantage bluetooth universal

Our comment: We’ve heard mixed reviews on the unique offering from BluVantage, which integrates Bluetooth technology for the first time.

Although we love the concept, it’s let down by somewhat buggy programming, and it’s something we’d personally prefer not to mess around with too much.

Since the old-school tried-and-tested boost controller methods work exceptionally well, modern technology can become extremely frustrating when it doesn’t work as intended.

Overall, a great concept and something that’ll certainly create a talking point at meets.

Would it be our personal choice? Unfortunately not.

With that said, it does have a reasonable price tag and means you won’t need to wire anything into the car or have any additional devices on your interior other than your smartphone.

Manufacturer description:BluVantage Technologies introduces the worlds first standalone bluetooth boost controller.

Featuring smartphone connection to control all your boost parameters using the BluVantage BluBoost app. With bluetooth 4.2 technology the BluBoost app can also double as a real time display boost gauge with absolutely no lag.

HKS EVC-S Electronic Boost Controller

hks evc s electronic

Our comment: For those interested in JDM goodness that don’t want to splash quite as much cash as the Greddy option above, HKS offers a more compact alternative to the market.

Suppose you’re after a more straightforward, compact unit that can still achieve most features of the most expensive alternatives from a premium brand. In that case, this could be an ideal option.

Although we’re not blown away by it, it’s still a fantastic product, but we would be spending a little extra on the Greddy above.

turbosmart in cabin

Our comment: TurboSmart brings the first manual boost controller to our list, with a unique offering that allows you to use a mechanical/manual boost controller from the driver seat.

Since this is a fraction of the price of the majority of the more expensive electronic options, this compact alternative could pose a real temptation.

Given that manual boost controllers are more of a set-and-forget type device, we wouldn’t expect to carry out many adjustments after initial setup, but this would undoubtedly make that process more convenient.

Manufacturer description:The Turbosmart Gated Boost Control Valve range is one of the best dollar for horsepower upgrades that you can make to your turbocharged petrol or diesel engine vehicle.

All Turbosmart Gated Boost Controllers feature our exclusive Gate feature which minimizes wastegate creep and can improve turbo response by up to 800 rpm earlier in the rev range – this means that you can increase the performance and response from your engine without even raising the maximum boost level.

TurboSmart e-Boost2 Electronic Boost Gauge/Controller

turbosmart e boost2 electronic gauge

Our comment: Although the e-Boost2 is the most expensive product on our guide, those running the likes of nitrous or methanol injection will want to make this a contender since it’s the only option in our guide capable of controlling these from the device.

If you’re simply looking for a boost controller with maximum features, we feel that several options will provide better bang-for-your-buck, such as the Greddy and AEM options.

Despite this, the ability to control the likes of methanol injection will undoubtedly be helpful to some, and it has a vast array of additional features to consider.

Our comment: TurboSmart’s cheapest offering is the plain and straightforward set-and-forget manual boost controller that will undoubtedly do a fantastic job at carrying out its essential tasks.

While this unit will remain in your engine bay, the in-cabin option above provides the same thing with the ability to adjust the boost from the driver seat, which you may also wish to consider.

If you’re looking for no-frills boost adjustment at a reasonable price, you really can’t go wrong here.

Manufacturer description:Smaller and lighter than other Manual Boost Controllers on the market. Set your boost and forget it. Boost adjustable from under the hood with an accurate, proven Detent System. Easy to install and adjust.

All Turbosmart Gated Boost Controllers feature our exclusive Gate feature which minimizes wastegate creep and can improve turbo response by up to 800 rpm earlier in the rev range – this means that you can increase the performance and response from your engine without even raising the maximum boost level.

Vibrant Performance Manual Boost Controller

Our comment: Offering a near-identical offering to the TurboSmart Boost-Tee above, this Vibrant Performance alternative makes another excellent choice for those looking for the more straightforward approach to tuning.

There’s barely anything to differentiate between the two products, including the price.

They’re both excellent value, and both brands carry a fantastic reputation. It could simply boil down to which item you prefer the look of.
