You have installed Aftermarket Camshafts and/or
Aftermarket Ported Heads, or Large Valve Heads.
Available for your 2013-14 Mustang GT!! Some customers are asking if
Sport Shifting is eliminated in our calibration. The answer is NO!!
Sport Shifting is retained and you will enjoy the increased shifting
pressure in your Brenspeed Calibration for Automatic Transmissions.
far the #1 first modification for your 2013-14 Mustang GT is a
Brenspeed tuned X3.
of as much as 30+ horsepower are possible with just our Brenspeed
tuned SCT X4 and add one of our air intake systems for another gain of
near 15 HP. Our custom tunes will give you the fastest throttle
response possible, increased HP, the maximum torque possible at lower
RPMís, and often improved MPG. Brenspeedís custom tunes are a far cry
from your basic aftermarket tune. We have years of experience and
R&D invested into our tunes to give you more benefits than just
a peak HP gain on the dyno. With multiple modifications performed to
many parameters within the torque management, adaptive learning, and
drive by wire tables it is common to reduce quarter mile ETís by as
much as a half second. Our custom automatic transmission tunes will
have your Mustang tire chirping at wide open throttle yet a nice firm
shift at light throttle. Our shift schedule also will keep your Mustang
more in the power range of the 5.0. You manual transmission owners are
not left out either, upon request we can eliminate your first to fourth
skip shift for those unwanted low rpm 4th gear shifts.
The Brenspeed Custom Tuned X4 includes one custom naturally aspirated
tune (NOT nitrous/turbo/supercharger) developed for your 2011+ Mustang
and then that tune modified for 3 various octane fuels. This way you
can run regular unleaded fuel if you desire or to take full advantage
of your package by running premium fuel. The SCT X4 will store the
factory tune so you can return the vehicle to stock at any time.
you are purchasing:
calibration developed in house on one of our engineering vehicles. We
have calibrations developed for almost every product we offer. Our
calibrations must pass a rigorous list of specifications through
racing, street driving, and dyno testing before they are released. We
do not simply dyno one car and consider that enough information for a
mail order calibration. This is the main reason that we do not
calibrate for every aftermarket product on the market.
we are constantly working on releasing new calibrations. A Brenspeed
standard calibration created by a software manufacturer that is
providing one size fits all "tunes" to everybody that purchases their
you are not
purchasing what is
known as a "remote tune" or "remote calibration". Remote tuning a car
is having the customer data log vehicle information and sending that
info to the calibrator, then changes are e-mailed back to the customer,
and so on. Remote tuning is the fine tuning of a calibration to a
specific customer need beyond the developed mail order calibration.
This is also known as dyno tuning, but with the tuner being remote to
the dyno or test area. Remote tuning and dyno tuning take about the
same amount of time and effort. We currently do not offer remote tuning
but we do have facilities located in Indiana that do offer in
house services starting at $400. Prices vary per application, and not
all applications are supported so please contact us for more
you order our sales department will e-mail you to find out about
your current modifications if any, your Mustang in general, and other
information so we can develop your custom tunes. The custom tunes will
then be loaded on your SCT X4 so all you will have to do when it
arrives is plug it in and allow the custom tunes to load on your
Mustangs PCM. It is that easy!
User adjustability so if you so choose you can adjust idle, axle
gear ratio, tire revolutions per mile, rev limiter, automatic trans
shift points, spark, and air fuel. Your custom tune will not require
any of these changes. We install the features on the programmer as some
customers like access to them.
