1 Brenspeed 2018-20 Mustang GT Custom Tune
Please Choose from the Drop Down Menu above if:
You have installed Aftermarket Camshafts and/or Aftermarket Ported Heads, or Large Valve Heads.
If you already have an SCT tuner then a custom mail order tune is a great option to free up power in your Mustang. You get the same great benefits as if you purchased your SCT tuner from Brenspeed and we will simply e-mail the tune to you along with instructions on how to install it on your programmer. 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.
*NOTE: If you have aftermarket Camshafts installed on your Mustang please select on the drop down list. Brenspeed has worked directly with Comp Cams to develop the premier calibration for their 5.0L cam line. 100% fully approved by Comp Cams.
What you are purchasing:
You are purchasing a
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. However,
we are constantly working on releasing new calibrations. A Brenspeed
Calibration is not a
standard calibration created by a software manufacturer that is
providing one size fits all "tunes" to everybody that purchases their
What you are not purchasing:
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
After 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.
Expedite Option: Typically all custom tuning orders are built in the order received. We understand that our customers sometimes have to be to a race, car show, or just want it fast. Because of time sensitive events we offer expedited custom tuning for an extra charge of $49. We will build your custom tune outside of normal business hours in order to give you a two business day turn around. If you choose this option please contact our sales department as soon as possible to provide us important tuning information.
