Can the S650 Mustang be Tuned?

Can the S650 Mustang be Tuned?

Last Updated July 29, 2025 | Kevin Brent

Enthusiasts always have mixed opinions on new Mustang models. The S650 Mustang, which launched in September 2022, is no exception. While some people love it, others have a variety of complaints, such as the price or the wheel package options. One of the biggest concerns originally was that the car had a locked ECU, which prevented traditional tuning for performance. However, recent developments have changed the landscape.

The S650 Mustang Can Now Be Tuned

HP Tuners has officially made progress in accessing the S650 Mustang's ECU. After months of work and speculation, they have successfully cracked the code and are now able to tune the platform. This is a huge step for the aftermarket community. While official off-the-shelf tunes are still in development and full platform support is being refined, tuners finally have a path forward for extracting more power from the 2024+ Mustang.

However, this doesn’t mean the job is done. There are still complexities involved due to the car’s advanced ECU and security architecture. But the once-locked S650 is now entering the tunable era, marking an exciting new chapter for Mustang enthusiasts.

What Is Ford's Position on Tuning?

Ford has remained cautious about allowing broad tuning access. While official Ford Performance Power Packs are expected, how those will be delivered is still unknown. With HP Tuners now gaining access, the hope is that Ford may become more open to third-party collaborations in the future.

When Can I Tune My S650 Mustang?

While there isn't an exact time frame for mass-market tuning, HP Tuners unlocking the S650's ECU means tuning is no longer a matter of "if" but "when" it'll be available. As more companies jump on board, we expect tuning support to become more robust and accessible. Until then, enthusiasts are going to have to stick to bolt-on upgrades to improve their S650's performance. Check out our top S650 Mustang mods for some suggestions.
