JMS BoostMAX for Ford's 2.3L EcoBoost motor is a plug and play solution to tuning your 2015 Ford S550 Mustang EcoBoost. If you prefer not to upload a tune file into your ECU then this JMS Focus ST BoostMAX 2.3L EcoBoost Performance Booster is the perfect solution for you because of its warranty friendly functionality.

This JMS Mustang BoostMAX 2.3L EcoBoost Performance Booster connects to your stock MAP, TIP and Pedal Connector in a matter of minutes. Once installed you will see a increase in vehicle acceleration, low to mid-range horsepower/torque, and turbo spooling time. This JMS BoostMax for your Focus ST allows you to add up to 5psi with the Remote Boost Adjustment Knob, which can be lowered as well.

With all the increase in performance you would expect lower MPG, but customers have actually witnessed a 2+ MPG increase on average. This BoostMax can also be stacked with JMS PedalMAX products to help with throttle response as well.

Note: If you have a custom tune already you can stack this BoostMAX in conjunction with your tune, but you must put put your boost to stock in your tune file to not over-boost your Ford Mustang 2.3L EcoBoost.
