2015-2016 Ford Mustang EcoBoost BoostMAX
Reduce turbo lag and improve the acceleration on your 2015-2016 Ford Mustang EcoBoost with the JMS BoostMAX. You can add up to 5 extra PSI of boost that adds up to 44 horsepower. The remote boost adjustment knob is included with the kit. This allows you to dial in your exact boost settings and enjoy the extra power "on the fly". The plug & play design makes for an easy install. All you do is connect the BoostMAX unit to your wiring harness.
Adjustable Boost Settings
-When adjusting the boost between the 50% to 75% setting, you must re-gap your spark plugs to .028" and use a minimum of 93 octane fuel.
-For settings over 75% on the adjustable knob, it is highly recommended to go to a colder spark plug. You can use the FRPP M1240520T, NGK 6510, or Denso ITV22 gapped at .028" and a minimum of 93 Octane fuel in the tank.
-This is a stand alone device and will NOT work with an aftermarket tuner or tunes.
-Not legal for sale or use in California or on pollution controlled vehicles.
After installing product The difference from oem is substantial. The instructions are vague and took about 3 hours. It is required to remove front shield, driver side front wheel and partially remove the wheel well liner to access firewall. Also, creativity is required for how and where you secure wires with zip ties.
Yes, I would recommend this item to a friend!
