Ford issued an ominous warning when it released the S650 Mustang about being able to tune it.
Upon release in 2022, Ford warned that it might be impossible to do so.
Three years later, some tuners in Florida have managed to crack the codes.
And the tuning shop has unleashed absolute mayhem with the S650 Mustang.

Aftermarket tuners jailbreak Ford’s system
The Ford S650 Mustang has finally been worked around by tuners.
HP Tuners has been able to work around Ford’s stringent electronic car controls.
Apart from tuning support for several other models, the S650 Mustang is the highlight.
Palm Beach Dyno is reportedly already offering tuning packages for pre-order vehicles.
These vehicles will come with 12 months of tuning support from Palm Beach Dyno.
They will also reportedly come with free-of-charge upgrades if they are available.
So, how much extra power has the company been able to squeeze out of the engine?
Well, they have managed to get 30bhp and 20lb-ft of torque from bypassing the electronic framework.
“We want more!”, Ken from PBD said.
Ford releases S650 Mustang with new electronics
When the S650 Mustang was released, Ford made some big changes.
Ford implemented its new fully Networked Vehicle (FNV) electrical architecture.
Instead of having individual modules only acting when told to do so, all modules were encrypted as a full stack.
To put this simply, it means that each module found it impossible to be rewritten.
If a tuner tried to alter an individual module, the others would detect it and shut down automatically.
This process essentially locked out tuners from being able to alter the performance of the Ford S650 Mustang.
Ford’s reasoning for this was to protect its vehicles and its profit.
Of course, Ford offers its own performance packages, but these are far from cheap.
According to reports, the aftermarket tuning from PBD will cost in the $300-750 range.
Road tests are expected to follow soon to ensure that the tuning is safe.
If proven to be safe, it is sure to be extremely popular with S650 customers everywhere.
