BoostMAX will increase the power output of your Ecoboost vehicle.
BoostMAX has been designed to be mounted with plastic zip ties
near the OEM ECU. The wiring harness plugs into two sensors on
the engine and then runs into the vehicle cabin through a drivers
side firewall hole and connects to the pedal sensor.

The concept behind BoostMAX:

• Add additional horsepower without reprogramming the ECU.
• BoostMAX connects to the MAP, TIP and Pedal Position sensors via a plug & play harness.
• Remote boost knob allows the user to add up to 5psi of additional boost (on the fly).
• 2.7L Ecoboost customers have reported gaining 50rwhp with the stock vehicle and BoostMAX (93 Octane).
• Add additional boost “on the fly” and when you want it.
• Use the remote boost knob to “dial-in” additional boost on the fly.
• Replace the remote boost knob with the Red Chip: 87 octane boost curve.
• Or remove the remote knob and red chip and enjoy the optimized 93 octane boost curve and more power!
• Simple to install, Plug and Play design that installs in just minutes.

Step 1

• Ignition key off, remove key from ignition.
• Open the vehicle’s hood.
• Disconnect the negative battery terminal.
• Remove the engine oil fill cap
• Remove the plastic engine cover and set aside
Note: Two 10mm bolts hold the cover in place.
• Replace the engine oil fill cap

Step 2

• Locate the MAP Sensor
The MAP Sensor is located on top of the black
plastic intake manifold, under the engine cover.
• Disconnect the OE MAP Sensor connector from
the MAP sensor.
• Connect the BoostMAX Wire Harness Labeled
“MAP Sensor” in-between the MAP Sensor and the
OE Connector.
• Use zip-ties to secure the MAP sensor wiring.
• Pictures show the Intake - MAP location on: 2.7L F150.

Step 3

• Locate the TIP Sensor on the 2.7L Engine.
It is located on the air-inlet tube near the throttle
body on the discharge side of the Intercooler (see
pictures 1 & 2)
• Connect the BoostMAX Wire Harness Labeled
“TIP Sensor” in-between the TIP Sensor and the
OE Connector (picture 1).
• Use zip-ties to secure the TIP sensor wiring.
Be sure to secure the wire away from heat sources
and or moving engine parts.

Step 4

• Connect the BoostMAX Module to the DB-25
connector, secure the screws with the screwdriver.
• Route the BoostMAX wiring harness alongside the
factory ECU (located on the firewall).
• Use zip-ties to secure the BoostMAX Module near
the factory ECU.
• When routing the wiring, be sure to stay away from
high heat sources (exhaust).

Step 5

• Route the flat four pin wire harness across the
back of the engine and pass it through the rubber
firewall grommet. Route the four pin wire through
the firewall grommet to the drivers side of the vehicle.
• Note: The firewall plug might be covered by insulation
on the inside. It may help to attach the
wire harness with tape to a stiff wire (coat hanger)
in order to fish it through the firewall opening (use
two people).
• Use zip-ties to secure the wiring.

Step 6

• Connect the Pedal Position Harness to the flat four
position main BoostMAX Harness (via flat four pin
connector, left side connector in the picture)
• Choose between connecting the Pedal Position
Harness to the Remote Boost Knob OR to the “87
Octane Red Chip”. (Right side connector in picture)
Note: In the picture the Pedal Position harness in
the center, the main harness plugs into the Pedal
Harness and then the Remote Knob Plugs into the
Pedal harness.

Step 7

• Locate the Accelerator Pedal Position Sensor
(Located on top of the Accelerator Pedal bracket)
• Disconnect the OE Pedal Position Sensor connector
from the Pedal Position sensor (pull the red tab
out and then press the black tab to release).
• Connect the BoostMAX Wire Harness Labeled
“Pedal Sensor” in-between the Pedal Position Sensor
and the OE Connector.
• Use zip-ties to secure the Pedal Position Sensor
wiring.

Step 8

• Route the Remote Boost Knob up and near the
center console. We recommend routing the cable
along side the center console (push the cable up
behind it) so you can adjust the knob “on the fly”.
• Use zip-ties to secure the Remote Boost Knob
wiring.
• Adjust the BoostKnob to the desired performance
level.
• Recommended knob settings: 87 octane = 50%,
91 octane = 90%, 93 octane = 100%.

Step 9

• Reconnect the negative battery terminal.
• Start and test the vehicle, it should function like
normal with additional WOT power. If the Ignition
Key is “ON” the Green LED on the BoostMAX will
illuminate ON.
• If the vehicle has a wrench light and no throttle: it
is due to disconnecting the Pedal Position Sensor.
• Turn the vehicle off, remove the key, wait 30 seconds
and restart the vehicle (the wrench light will
automatically clear itself on restart).
Enjoy the extra plug & play BoostMAX power.

Recommended Spark Plug and Spark Plug Gap for BoostMA X

This information applies to all 2011-2015 Ford F150 3.5L EcoBoost equipped trucks and 2010-

2015 Ford Taurus SHO 3.5L EcoBoost equipped cars. To eliminate the potential for ignition misfires commonly known as “spark blowout” at high RPM levels when running a JMS BoostMAX we recommend replacing the sparkplugs and setting the plug gaps as listed below in the chart.

Please call us at 601-766-9424 for more information on Ecoboost 1.6L, 2.3L & 2.7L engines.

Note to Focus ST 2.0L Ecoboost owners

If you stay under high boost for longer than 15 seconds, your vehicle may go into overboost mode and the power/boost will be automatically pulled back by the factory ECU. This is a feature of your control system. To solve this issue, you will need a custom JMS ECU tune via an X4 stacked with your BoostMAX unit. The two units together provide the ultimate in performance for the Focus ST.

• Simple to Install product that supports all Ford Gas & Diesel vehicles
• Does not void vehicle warranty
• Optional Single or Dual Remote Pedal Knob
