    Sizzling Performance. Putting some extra punch into your already fiery 2015-2019 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 2015-2019 Mustangs equipped with the 2.3L EcoBoost.

    5 Top Rated Questions

    • The JMS BoostMAX Performance Booster (Race Version) is compatible with 2018 EcoBoost models, in addition to 2015-2017 EcoBoost models.

    "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?

    • 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.

      Doesn't flash your ECU.

      Significant noticeable power gains with out making any undo able changes! I'm using the red 87 octane chip running 90 octane ethanol free gas and my gas mileage went up when I'm not in the turbo using the cruise control. I'm planning to get a Ranger later this year and this will be my first mod. Excellent Product!

      Smooth Fast

      I spent 2 hrs fpr installation because I got some troubles with the Engine light and Wrench Light show up after first trying. But after all, those light went off. After the installation,I gave my car a ride test and i can feel a lot difference,more smoother and felt faster. P/s: for installation,when you guys plug all the cable into place and try to start the car,if the engine light and wrench light show up,try to unplug all the cable and plug it back after 30s. If it still show up,repeat that step. It will go off.

      Love it

      It does work I hit 22/24 psi maybe fuel is better but I floor it all the time and drive hard with other little work the ecoboost can beat the 5.0 to 70mph after then the 5.0 takes over some times I go into overboost and have no turbo boost at all and I have to pull over turn the car off then back on Maybe 4 times now over in 1 year

      Smooth and Fast

      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).

      Josie Wails

      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!!
