Ford Mustang Tuners – Guide For Owners Of Different Generations!

Written by Jeff Glucker

How to Tune your Mustang?

You might have any model dating from the original in 1965 to the latest 2019 Bullitt, whichever model you have, there are always more ways to improve performance. While some will call this sacrilege, others will claim its necessary. Sort of like taking a top athlete human and juicing him/her with steroids. No matter which school of thought you belong to, the fact is you can upgrade Mustangs as you upgrade any vehicle.

There are three ways to perform an upgrade; the first is to install aftermarket parts which are designed to increase power and performance. The second is to use a tuner for improving the specs of the vehicle through its electronic interface, and the third option is to perform both.

I won’t delve on aftermarket upgrades; this article is all about the best tuners for Mustang tweaking.

A bespoke tuner will increase your power and torque, improve your throttle response, provide a more aggressive shift point in automatic models only, and optimize for fuel economy. The bottom line of a tuner is to pull out every ounce of power and performance from the engine and parts you already have, or replaced with aftermarket parts.

Also consider reading these articles:

What can be tuned?

Essentially, any part can be tuned for performance, and this includes
Camshafts, Cold air intakes, Cylinder heads, Fuel injectors, Full exhaust systems and headers, Intake manifolds, Nitrous systems, Rear gear changes, Superchargers/Turbochargers, and Throttle bodies.

This is the performance list, there are other options to add such as automating windows, locks, alarms, etc., but that is for comfort, not performance.

A tune, when applied properly will increase your Mustang’s power and the performance range from 12-35 HP/TQ.

Take heed that tuning your Mustang will void its warranty, and understand this, Ford has proprietary software that will know when you tuned, and how many times you tuned and restored.

Custom, Canned and Dyno

There are three types of tunes available, these are:

  • Canned: A generic preset tune that comes with the device.
  • Custom: A specially written tune, either prepared by a company or made by a professional.
  • Dyno: A shop prepared tune, where the tuner dials it in real-time.

Take heed: Never buy a tune from an unknown source, and never tune by yourself. Custom tuning is for professionals that understand the nature of the entire operation; one change can destroy your performance, let alone an entire range of changes.

Tuning Years

From 1996 and onwards, Mustang cars come with PCM ODBII connectors, so for these models, you only need to plug and play. Anything older will require a special treatment not provided by a tuner.

Tuning Variants

There are two variants for tuning; one is the use of chips, which come with preset tunes that you can employ at the flick of a switch. These are closed circuits, which means you cannot make custom adjustments. The second variant is Tuners, which come with open circuits that allow you to make custom changes to specific options.

Now let’s look at the 5 best Mustang tuners on the market today.

The original Ford Mustang I two-seater concept car was developed in 1962. From this day on the world of muscle cars changed. The original design evolved very quickly into the 1963 Mustang II four-seater concept car. These two launches were interesting, but it was in 1965 that Ford finally hit the market with its GT350 model.

This model started with the Mustang fastback. Its designer Shelby added quicker steering, a sportier suspension, and larger brakes. It was powered by a stock 4.7-liter V8 engine that delivered a massive 306 horsepower by adding a high-rising intake manifold and a four-barrel carburetor. This 1965 model is a collector’s item and is one of the most popular Mustangs on the market. In 1968, Ford produced the first Mustang Cobra model which came with a 335 horsepower engine.

In 1969, Ford introduced the Mustang Mach 1. The 1969 Mach 1 featured a new aerodynamic body called the SportsRoof which was supplemented with a 428 Super Cobra Jet V8 engine delivering 335 horsepower and 440 pound-feet of torque. While these figures were impressive back in 69’, they are still impressive today. In 1971, Ford followed through with a heavier version, and then in 1974 delivered the Mustang II, which was also named Cobra, but this was a smaller hatchback model with a 2.8-liter V6 giving 105 horsepower.

The next big change came in 1984; the Mustang SVO came with a 2.3-liter turbocharged four-cylinder engine delivering 175 horsepower at 4,000 rpm and 210 pound-feet of torque at 3,000 rpm. This turbo four models delivered the same power as the 5.0-liter V8 but was much lighter.

Enter the Cobra R in 2000; this is the Mustang SVT Cobra R. It was this model that finally propelled Shelby into the automotive hall of fame, and came as a limited edition. The years rolled on, and ion 2016, the all-new Mustang GT350R was introduced to the world.

The Shelby GT350 Mustang was designed as a modern reflection of the original Mustang model GT350. What makes this model special is the 5.2-liter flat-plane crankshaft V8 engine which delivers an incredible 500 horsepower and 400 pound-feet of torque using a six-speed manual transmission with a Torsen limited-slip differential.

In 2018, Ford introduced the next stage Mustang; this is the 2019 Mustang Bullitt. This model comes in many variants, the core of this model is Its 5.0-liter V8 engine providing 480 horsepower and 420 pound-feet of torque to the rear wheels. However, this model uses a six-speed automatic transmission.

The 2019 Ford Mustang comes in 8 variants, these are:

  • 2019 EcoBoost®: Fastback, Premium Fastback, Convertible, Premium Convertible
  • 2019 GT: Fastback, Premium Fastback, Premium Convertible
  • 2019 Bullitt

  • Good article. However, the 2019 Mustang Bullitt edition is equipped with a six speed manual transmission. An automatic is not offered or available for this model. The GT and GT premium can be equipped with an optional 10 speed automatic transmission.

    • Hi Eric,

      Good point! It is possible, but it’s not an off-the-shelf solution – you can’t just buy it on Amazon or elsewhere and install it like any replacement part. There’s a whole guide that needs to be written so I’ll just remove it for now.
