The JMS BoostMAX Performance Booster with controller is available for the 2015 or newer
2.7 liter EcoBoost-powered F-150 owner who's looking to reduce or even eliminate the pedal
lag that keeps your truck a little sluggish off the line.
This device has different modes to help get that job done and it makes the driving experience
so much more enjoyable with very little effort and absolutely no tune required and JMS claims
it even adds up to 50 horsepower.
So, we're gonna install it, take it on the dyno, see what it makes.
Now, as for the installation, I am gonna give it one out of three wrenches on our difficulty
meter which I'll walk you through later on.
On the dyno, we established a baseline run in our 2015 2.7 with 87 octane and a stock
tune and it made 270 horsepower and 337 foot pounds of torque at the wheels.
With the JMS device installed at its highest setting, it made 325 horsepower and 398 foot
pounds of torque at the wheels.
That means we're looking at peak gains of 55 horsepower and 61 foot pounds of torque
and 38 horsepower and 64 foot pounds of torque under the curve.
Pretty impressive gains here from the JMS device.
And just as you want with these big rigs, the big torque gains are down low at around
the 3,000 RPM range as you can see by this graph.
That definitely helps us gets off the line a lot quicker and the boost really makes a
difference as you can tell.
Now, with all that said, here is exactly how the throttle device works.
When you're driving your F-150, you've probably noticed there's a slight lag time between
the time you hit the pedal and the time that your throttle body actually opens and your
truck accelerates.
This is the drive-by-wire delay and it's exactly what the BoostMAX can fix.
This device from JMS plugs right into your OBD two-port under the dashboard and bridges
the gap between the moment you want your truck to go and the moment it actually does.
This will override the drive-by-wire and allow you to choose how much more responsive and
how much more boost you want there to be in your throttle.
And you'll have the ability to set it anywhere from 0% being stock and 100% being full out
race mode which adds the max boost of 5 psi, which is where the power gains comes from.
Now, all that can be done on the remote knob itself as you can see here.
The delay is there because the gas pedal is controlled electronically by sending a signal
to the ECU, which then sends the signal to the throttle body.
You'll see significant throttle response gains getting you off the line a lot faster, while
also reducing turbo lag as well.
So, this overall can be a huge help for your EcoBoost-powered truck.
Now, when you plug the device in for the first time, it will automatically be set at the
maximum throttle increase setting right out of the box.
Obviously, you could hop on the road and test it out first but be aware that this is going
to make your pedal extremely sensitive, so you might wanna proceed with caution at first
because it can be no joke on 100%.
Trust me, I've tested these devices and I know that it can really change the driving
experience.
Another way to get better boost experience is by replacing the remote knob with the red
chip for an 87 octane boost curve or you can remove both the remote and the chip for a
full 93 octane boost curve.
These devices from JMS are also stackable which is extremely beneficial.
What that means is you can install this and use a custom or pre-loaded tuner with your
truck and still take full advantage of the performance booster.
The work in conjunction with most aftermarket tuner devices like SET, DiabloSport, Edge,
Superchips, Bully Dog and so much more.
Now, each device has JMS' state of the art digital technology sealed right inside an
airtight housing.
As you can see, you get plenty of plug and play harnesses here which means you literally
just plug it into the OBD two-port, connect the bunch of harnesses and the OEM connectors,
and, of course, you're good to go.
It's pretty simple.
It's also completely reversible too because all you'll have to do is just unplug it and
everything goes back to stock like nothing ever changed.
You can grab one for yourself for just over the $300 mark, which I know sounds like a
lot, but it is less than a tuner and you completely change how you get off the line and accelerate,
plus it adds horsepower with the given boost.
Now, again, I've driven one of these before and it really does make the world of difference.
Obviously, a custom tuned would actually add a little bit more and maximize all of the
mods you have done to your truck.
This does however add power, again, up to 50 horsepower as claimed by JMS.
And as you saw from our dyno numbers, it's very, very accurate.
Obviously, a custom tuned would encompass all of the mods done to your truck but then,
again, this does add some boost here up to 5 psi depending on the settings.
So it does have its worthwhile on the dyno as you saw earlier.
For the install, I'm no doubt giving this one out of three wrenches on our difficulty
meter.
You should be able to tackle it in about 30 minutes or so with a ratchet and simple socket
set.
You'll start by popping open your hood, disconnecting the negative terminal on your battery, then
locate the map sensor by removing the engine cover with a 10-millimeter socket, disconnect
the sensor from the connector, then connect the BoostMAX wiring harness labeled map sensor
in between the sensor and the OE connector.
You can use the zip ties provided to secure that wiring.
Locate the TIP or TIP sensor on the air inlet tube near the throttle body on the discharge
side of the inner cooler.
Connect the BoostMAX wiring harness labeled TIP sensor in between this stock sensor and
the connector, then zip tie it back away from the heat sources nearby.
Connect the device and the DB25 connector and secure the screws with a screwdriver provided
by JMS.
Run the wiring harness alongside the factory ECU on the firewall, then zip tie the module
near the ECU.
Run the flat four pin harness across the back of the engine and pass it through the rubber
firewall grommet to the driver's side.
Connect the pedal position harness to the flat four boost max harness.
Then you can choose if you wanna connect the remote knob to the device or the 87 octane
red chip.
Remember that using neither of these chips activates the 93 octane boost mode.
Now, disconnect the OE pedal position sensor connector from the sensor and connect the
BoostMAX wiring harness labeled pedal sensor in between the pedal sensor itself and the
OEM connector, then zip tie it to secure it just like the other ones.
Run the remote knob off the center console, so it's in arms reach while driving if you're
using it.
The JMS recommends using 50% for 87 octane and 90% for 91 octane and, of course, 100%
full boost for 93 octane for the best results while using the controller.
Reconnect the battery terminal and then you're good to go.
That just about wraps this one up.
So if you're the owner of a 2015 or newer 2.7 liter EcoBoost F-150, you might wanna
