Let's F*cking Go
The second the S650 dropped, people were hyped.
Everyone knew the 2024+ Mustang GT and Dark Horse had potential, but Ford slammed the door on custom tuning and locked out the entire aftermarket.
No power. No freedom. Just a stock file, or a blower tune with no wiggle room. No custom mods. No fuel flexibility. No remote support.
Forums lit up with complaints. Tuners gave up on it. People said the S650 was a dud.
They were wrong.
Tuning Is Now Unlocked
Tuning is now unlocked for the 2024-2025 Mustang GT & Dark Horse, and now available for select Ford trucks and SUVs. Newly supported platforms include:
- 2025 Explorer ST 3.0L
- 2024-2025 F150 (5.0L)
- 2021-2025 Bronco 2.7L
- 2022-2025 Bronco Raptor 3.0L
- 2022-2025 Ranger Raptor 3.0L
- 2021-2023 F-150 (2.7L, 3.5L, 5.0L)
- 2023 Raptor R 5.2L
- 2022-2023 Expedition 3.5L
This isn't some beta-access workaround or limited-use blower file. This is the real deal: full custom tuning, built specifically for your mods, your fuel, and your goals.
Backed by the most trusted names in the tuning game, Lund Racing, Shoemaker Performance, and Palm Beach Dyno, we're finally able to deliver what the S650 platform was always capable of. With support from the new Lethal Performance RTD4, we're doing what everyone said was impossible.
TL;DR: The S650 is unlocked, and it's not alone.
You can now custom tune your 2024-2025 Mustang GT or Dark Horse with full control over fuel, boost, and revisions. Support is also live for Bronco, F-150, Ranger Raptor, Expedition, Explorer ST and more. The locked ECU era is over.
The Key to the Kingdom
Meet the Lethal Performance RTD4
