Please see below for drop down menu options and explanations.

Ford has really outdone itself on the GT350 Mustang. The combo of the 5.2L engine and amazing appearance makes it a great car but there is always room for improvement.

Our Stage 1 GT350 package tweaks the calibration for ultimate performance as well as opens up the induction with the ever popular JLT Cold Air induction system.

Our package starts out with your choice of the SCT X4 or BDX programming device. Both devices will deliver our Brenspeed custom calibration to your vehicle the same but the BDX is the newest offering from SCT. Once you order we will need some important information about your GT350. Differences? The X4 has been around for years and has data logging capability as well as the ability to read check engine lights on most any Ford vehicles. When we email you the Brenspeed calibration you use free software we provide to load the Brenspeed calibration on your SCT X4 programmer based off the information you gave us when you received the device. The BDX is wifi capable which means we upload your calibration to a cloud and the devices wifi capability will download your custom calibration directly to the device without plugging the BDX into a personal computer. It still has all the features of the X4, but the wifi capability makes life very easy. If you want the newest and the best choose the BDX from the drop down above for no extra charge.

After you order we will ship your package and request some information via email about your GT350. The SCT programmer of choice will be shipped to you blank and once you provide the information we will create you a custom calibration for your GT350 that will be designed for the high flow JLT Cold Air Intake. Benefits of the calibration are….

Improved throttle response

Modified Torque management tables to allow the max amount of power and torque possible at all RPMS

Modified cam timing curves for max torque at low rpm as well as improved peak horsepower

Although fuel mileage may not be a concern, fuel and timing tables are optimized at cruising speed for the best available efficiency.

Cooling parameters are adjusted to provide the maximum cooling in street and competition environments.

Spark curves are optimized based off of your desired octane fuel you choose to run in your GT350.

Race fuel is an option as a drop down for the die hard road course or drag race enthusiast. The calibration will be adjusted for your specific fuel. (exact fuel type information is needed).

This package includes a high flow JLT Cold Air Intake. The JLT intake is fully computer designed to optimize power, space, and appearance. It is available in a standard black plastic inlet with heat shield and a huge 4.5” inlet at the throttle body. The heat shield features a cold air inlet duct to keep your intake temperatures as cool as possible. The filter opening is 5” and the inlet pipe is available in a painted finish to match the exterior of your car, or a carbon fiber “hydrocarbon” finish to resemble real carbon fiber. If you want to upgrade over standard textured black just use the drop down above.

After you order our sales department will ship you the Stage 1 package and then 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 calibrations. You will also be able to choose your octane fuel during this time. Once you receive your SCT device simply follow our instructions on how to prove us your vehicles information and we will email your calibration or upload it to the cloud if you choose the BDX.

Optional Drop Down Menu:

Expedite: This expedites your order to approximately 1 business day. Standard lead time is 5 to 7 business days from when we receive your vehicle information. Expedite is a good option if you are in a rush to get your vehicle up and running.

Race Fuel: If you are serious about performance choose this option and we will provide you with a calibration designed for your race fuel. We will need to know exactly which race fuel you intend to use. We use revised cam timing curves, engine spark tables, knock sensor programming, and fuel curves to optimize power for race fuel.

Data Logging: If you are interested in data logging your vehicle use this option. We will provide you with a data log configuration file that can be used with the SCT device and software to record vehicle information. We will review, and adjust the calibration if needed based off of the information you provide. This is how we calibrate vehicles on the dyno but this is called remote tuning or remote calibrating. Although our e-mail calibration is within a few percent of optimized our data logging option is a good when you are looking for max performance to your specific vehicle. Note: This is not an ongoing service for the future as you further modify your car. This service is for the initial calibration you purchase.

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 tuning software.

This process is very easy. Order online, we ship it, you provide vehicle info, and then we supply the Stage 1 calibration so you can install that as well as the JLT cold air intake on your GT350. Instructions are provided or give us a call if you have questions.
