Sizzling Performance. Putting some extra punch into your already fiery 2015-2017 Mustang EcoBoost is as simple as attaching the JMS BoostMAX Race Version Performance Booster, which improves vehicle acceleration and low or mid-range torque and horsepower. Amplifying the boost by up to 5 PSI, the JMS BoostMAX generates up to +44 RWHP (rear wheel horsepower). This performance booster also cuts down on the turbo lag often experienced in EcoBoost Mustangs and adds +2 MPG fuel efficiency in many cases. It is designed to be stackable with other JMS boost devices, plus SCT flash tuners, in order to generate even bigger horsepower and torque gains.

Convenient Design. The designers of the Race Version JMS BoostMAX made it with convenience in mind, including a plug-and-play install and a remote boost control knob. The control knob enables instant adjustment of performance and power with the booster installed. An 87 octane red chip is also included to optionally improve 87 octane function. The BoostMAX features a green status LED and can be installed in your Mustang without affecting the vehicle's warranty.

Simple Installation. The JMS BoostMAX is a plug and play component that comes complete with a wiring harness, install kit and instructions. Installation takes just minutes and involves unplugging the TIP, MAP and Pedal connector and plugging in the BoostMAX in its place.

Application. The JMS BoostMAX Race Version Performance Booster is designed to boost the engines of 2015-2017 Mustangs equipped with the 2.3L EcoBoost.

I have this stacked with a Bama X4/SF4 Power Flash Tuner, performance tune and the acceleration is the most noticeable (which I love). I haven't driven long enough to notice a change in fuel economy. ...

"This performance booster also cuts down on the turbo lag often experienced in EcoBoost" A) Does anyone have any figures they could provide, I am installing mine in a couple weeks and want to be able to compare. B) How does this effect 0-60 and 1/4 mile times?

MatthewT

  • The JMS BoostMAX Performance Booster is adjustable to provide up to an additional 5PSI of boost which can add up to 44 additional HP. 0-06 and 1/4 mile times will improve, however due to a number of variables such as tire size and type, suspension, road surface, temperature and humidity, as well as elevation, hard numbers can not be attributed to this.

Would it be okay to run the JMS BoostMAX Performance Booster with an Unleashed tune at the same time?

What is the big difference compared to the standard JMS BoostMAX?

minidave

  • JMS BoostMAX - Race Version is more aggressive and has a better throttle response than the boost max. Also includes a option for 87 octane fuel.

I purchased a bama x4 to tuner and bama notified me it isn't safe to run their custom tunes with the boostmax plug and go. Is there any ideal tunes to run with the chip that won't be detrimental to my engine performance?

  • You would have to check with the tuning company you are trying to use.

After I installed this product the Green light comes on, but the second red light also comes on. I shut the car off for 30 seconds like the instructions say and after I restarted the car the same two light come on. After testing my car, I felt no performance gains. What should I do?

CristosK

Is there an on/off switch for this? I only want to use it on the drag strip. Do I have to completely disconnect/uninstall the unit for everyday driving?

  • Hello! The JMS BoostMAX Performance Booster has a boost knob that will allow you to turn the boost down to 0 for street driving.

    I have this stacked with a Bama X4/SF4 Power Flash Tuner, performance tune and the acceleration is the most noticeable (which I love). I haven't driven long enough to notice a change in fuel economy. The turbo lag also seem non-existent at this point which makes it's smoother. For easier installation, get something legit to raise the front of the vehicle (I parked my front tires up on a curb with the E brake on).

    Added the JMS BoostMax to my 2016 Ecoboost Mustang named Josie and what a difference it makes. The installation was easy and the horsepower increase is noticeable. There has been an added benefit in that when I resist the urge to keep my foot planted to the floor, my gas mileage has increased 2-3 mpg. Just unreal results for one hours work.

    JMS brings your mustang to life!!

    The JMS boostmax was a little difficult to install. I recomend having a lift to install this or a jack. This product really made my car come to life though. I got peak gains of 43 rwhp and 57 lb of torque with 93 octane. This product will leave you speechless!!
