only offer calibrations for 1999-2004 Mustang GT's and V6's with
STOCK injectors, and STOCK OEM MAF's. This calibration is for stock OEM
engines and not conversions.
the #1 first modification for your Mustang is one of
our aftermarket air intake and custom Brenspeed tuned X4. 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, spark, and fuel tables it is
common to reduce quarter mile ET's and often improve MPG.
Brenspeed Custom Tuned X4 includes one custom naturally aspirated
tune (not nitrous/turbo/supercharger) developed for your 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. What
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.
