Top 5 Best Manual & Electronic Boost Controller Kits Reviewed & Ranked by Car Enthusiasts

Last Updated on Aug 16, 2023 By Lillian Kazmierczak

Even in today’s day and age, most vehicle manufacturers take certain measures that disable the users from using their vehicles to their full potential. Although the makers might have all the good reasons for doing so, many motorists oppose this idea and lean towards external automobile parts that enable them to get the performance they expect from their beloved vehicles.

Boost controllers are one of the most common examples of those external motor parts that help you enhance your car’s performance. These devices increase the boost in the engine by simply misguiding the wastegate to stay closed for a longer period. Over the years, they have been developed and upgraded to a certain extent that reduces the chance of damaging the engine. That’s why they have gained a boost in interest among motorists in the last few decades.

However, the risk of overusing the engine’s stock power still remains if your boost controller isn’t configured according to your vehicle’s specs. Besides, every model or type you might find on the market won’t suit your vehicle. So, heading into the market in search of the best boost controller without proper knowledge won’t do you any good.

Here, we have narrowed down the names from thousands to just five and came with a list of the five best boost controllers you’ll ever find. We’ve also shared our experience with these products so you can draw a picture of how good they’ll work for you.

04 GrimmSpeed 070002 Manual Boost Controller (Top Manual Choice )

GrimmSpeed 070002 Manual Boost Controller-Black

Why It Stands Out to Us

The Grimspeed 070002 is one of the best manual boost controllers you’ll ever find. Coming from a brand that has earned its popularity by manufacturing excellent professional racing vehicle parts, you know you can trust this device.

For starters, it looks nothing like the other manual boost controllers on the market. Grimspeed has used quality materials in this controller that can withstand incredible pressure. You’ll find it really easy to install and adjust. Performance-wise, it’s second to none. You can crank the boost level up to 60PSI if your vehicle can take that kind of pressure.

The most exciting thing about this controller is that it costs less than $100, which is a small price to pay for the performance it provides. If you’re aiming to purchase a manual boost controller, the Grimspeed 070002 is your best bet.

Our Experience With the GrimmSpeed 070002

  • The device came with great packaging and in good shape. We loved the fact that it didn’t look like most other manual boost controllers. The material seemed solid and sturdy enough to withstand great pressure.
  • We downloaded the manual and gave it a read. It answers all the questions you might have about the product. There was every detail of the installation and mounting written in the manual.
  • Installing the 070002 was a piece of cake. It took less than 10 minutes to set up the device in any vehicle. We faced no issue attaching it to the vacuum hose and it was ready to be tested in no time.
  • Where most other manual boost controllers struggle to achieve 30PSI, we could crank the boost level all the way up to 60PSI with the Grimspeed 070002. Make note that we only tried this in the vehicles that are capable of withstanding that pressure.
  • With every click, the Grimspeed 070002 provided 0.25 PSI. Twisting it clockwise gave us an increase in the boost. Similarly, when we needed to reduce the boost level, twisting it anticlockwise did the trick.
  • There was a noticeable improvement in the response of the vehicles. The response and spool-up were quicker than before and horsepower and torque increased massively. The vehicle also sounded better with the increased boost.

What We Didn’t Like

  • The click didn’t make the ratcheting sound that we expected. This sometimes made it hard to determine where we were with the boost level.
  • Like all manual boost controllers, this one needs some expertise to use. So, it’s not really a great choice for amateur motorists.

What Could Be Improved

  • Grimspeed could indicate the inlet and outlet on the device itself.
  • The click sound could be a little louder.

Our Recommendations

  • Make sure to keep the vacuum hose as short as you can. This will help the device perform at its best.

05 NXS Motorsports Signature Series Manual Boost Controller (Budget Pick)

NXS Motorsports Signature Series Manual Boost Controller

Why It Stands Out to Us

Finding the best vehicle parts on a budget can get tricky because most budget-oriented automobile parts often fail to provide optimum results. However, the manual boost controller from NXS Motorsports surfs against the current as it comes at a low price and performs like a beast at the same time.

With sturdy construction made of 440c stainless steel, this boost controller handles boost levels up to 30PSI. You’ll find it very easy to install and use. This small device can improve the horsepower and torque in your engine instantly.

Apart from that, the manufacturers have included a lifetime warranty with the product that tells you how much confidence they have in their product. If you’re looking for the best value for your money, make sure you go for the NXS Motorsports Signature Series Manual Boost Controller.

Our Experience With the NXS Motorsports Signature Series Manual Boost Controller

  • The product came in really good condition and the packaging was great as well. It featured a pretty traditional look. The materials used in the boost controller felt premium and very sturdy.
  • We downloaded the user guide and we have to admit that NXS Motorsports did a very decent job making it. The user’s manual had every bit of information we needed about the boost controller.
  • The NXS boost controller had one of the easiest installations in all the manual boost controllers we used. Both the inlet and the outlet were very easy to connect to the hose. We faced no issues tying the unit with zip lines as well.
  • The adjuster looked like a bolt and twisting it was way easier than the adjusters in most of the manual boost controllers we reviewed. Twisting the adjuster clockwise increased the boost and twisting it anticlockwise reduced the boost levels.
  • For how low priced it was, we were very satisfied with the maximum boost levels the device could achieve. We could get a maximum of 30PSI with the NXS boost controller.
  • In terms of performance, there wasn’t anything to complain about. With an increased boost, the engine worked great. Horsepower and torque increased significantly as well and the noise that the turbo made was very satisfying to listen to.

Do You Really Need Boost Controllers?

Just like the name suggests, a boost controller simply controls the boost of a vehicle. It is a simple mechanical or electromechanical device that channels the flow of pressure from the compressor of a turbo engine to the wastegate actuator.

If you don’t know what a wastegate is, it’s a mechanism that acts like a gate that opens and closes to maintain the pressure levels in and around the turbo. If the pressure level of the exhaust exceeds the configured pressure level in the actuator, the wastegate opens to channel the exhaust around the turbine and decreases the boost.

The main purpose of having a boost controller is to manipulate the wastegate by flowing the amount of pressure that won’t trigger the gate to open. For example; if the wastegate opens at anything more than 5PSI, configuring the boost controller’s output to 5PSI will keep the wastegate close even if the actual pressure flowing through the turbo is more than 5PSI.

Different Types of Boost Controllers

Types of Boost Controllers

i) Bleed Boost Controllers

Like all other boost controllers, these manual devices are installed in the vacuum line of the wastegate. They can be used anywhere on the line but typically they’re kept near the wastegate. The bleed controllers bleed off pressure from the line and keep the wastegate close.

For a better understanding, let’s say a bleed-type controller is installed in a vehicle that uses a wastegate, which opens at 10PSI. If the controller bleeds off 2PSI of gas, the turbo will have to produce 12 PSI of gas to open the wastegate. This procedure will increase the boost of the vehicle by 2 PSI.


  • Boost pressure stays solid
  • Causes less boost spiking


  • Doesn’t assist spool response as much as the other types of controllers

ii) Ball and Spring Boost Controllers

These controllers are completely manual and use a ball and a spring to control the air pressure. The ball stops airflow until the point when it’s overpowered by the pressure. These controllers are vacuum lines of the wastegate, just like their bleed counterparts.

The ball and spring boost controller is configured by tightening the spring. As the tightness in the spring increases, the required pressure for the turbines to unlock the wastegate increases as well. This forces the turbo to generate more pressure than usual.


  • Instantly adjusts boost pressure
  • Makes the turbo more responsive


  • Prone to issues like over-spiking

iii. Electronic Boost Controllers

Electronic boost controllers from different manufacturers operate differently. To generalize how they work, it can be said that these electromechanical devices hide the actual level of pressure from the wastegates just like the ball and spring boost controllers until the boost level exceeds a certain point.

However, when and if the pressure reaches the point where it can be harmful to the vehicle, the software part of the device kicks in and commands the mechanical part to open the wastegate. Unlike the manual ones, the electronic boost controllers keep the boost in check and save the vehicle from damages.


  • You can control it from inside the car
  • Increases spool and boost response better than any other controllers
  • Works great in suppressing the boost spiking


  • Installation can be difficult


Any boost controller – whether manual or electrical – comes with a certain degree of threat to the vehicle itself.  If the device is not configured according to your vehicle, it can damage the vehicle and even destroy the engine.

As a rule of thumb, turbocharged or supercharged engines are by nature set to a “high performance” mode that generates a lot of power. Cranking up the boost to an extensive level can increase the temperature to an extent that could damage the engine or other smaller components.

On the flip side, lower-performance vehicles do not feature the extra horsepower that’s needed for the additional boost you’re aiming to get with a boost controller. Increasing the boost without having that stock power can spoil the engine completely. To avoid such problems, make sure to do full research on your vehicle and determine if it’s ready for the kind of boost you’re trying to achieve.


Boost controllers are one of those automobile parts, which are difficult to put a warranty policy on. In most cases, budget-oriented boost controllers don’t come with any warranties. But products with bigger price tags can give you up to 1-5 years of warranty depending on the manufacturers.


You’ll find a lot of varieties in terms of price range on the market for boost controllers. It goes without saying that manual boost controllers will cost you less than electric ones. Depending on the quality and the brand, a manual boost controller can cost you from 20-200 dollars. On the flip side, for an electric model, you’ll have to spend 100-500 dollars.


Q. 1: Does a boost controller increase engine power?

Ans: Using a boost controller in a turbocharged or supercharged engine can increase the rpm in the turbine and the horsepower of the engine. So, it’s safe to say that boost controllers can enhance the abilities of the engine.

Q. 2: Are manual boost controllers safe?

Ans: Manual controllers are the most commonly used type of boost controllers out there. These devices can be a threat to the engine if they’re not tuned properly. But if configured properly, manual boost controllers do no damage to your vehicle.

Q. 3: Do I need a boost controller with an external wastegate?

Ans: Most external wastegates feature larger springs and actuator diaphragms that can handle greater boost pressure than those of the internal wastegates. However, a boost controller can be used to increase or decrease the boost of a vehicle. So, it’s pretty normal to use a boost controller with an external wastegate.
