As Ford Authority was first to report back in October 2022, the S650 Ford Mustang was destined to be “much more difficult” for third party companies to tune compared to prior generations due to the fact that the newest pony car utilizes the company’s Fully-Networked Vehicle (FNV) electrical architecture. The beefed up security stemmed from the need to prevent hackers from committing cyberattacks via the over-the-air update capability presented by that architecture. However, that code has now been cracked, and Steeda is set to become the first company to test the new Mustang tune on a track.
As Ford Authority was the first to report earlier today, HP Tuners just announced that it has developed tuning support for the S650 Mustang, as well as a handful of other Blue Oval models utilizing FNV. Steeda already has their hands on this Mustang tune, and the long-time supporter of the iconic pony will also be the first to test it out on the track, Ford Authority has learned.
Steeda is set to test the new S650 Mustang tune in the Performance Driving Group of its HPDE car – aptly named White Stallion – on Saturday, July 12th, at the Homestead Speedway outside of Miami, Florida. This will be the very first time the S650 Mustang tune is tested by anyone on a real-world track.
Steeda tells Ford Authority that White Stallion is already handling very well, outrunning various competitors in the corners. However, it’s come up relatively short on the straights. Given the fact that Steeda expects to gain 28 horsepower from the new tune, that should certainly help the HPDE car keep up on the straightaways. As Ford Authority reported earlier today, Palm Beach Dyno managed to quickly extract around 20 horses from Steeda’s White Stallion on the dyno with this new tune, so there’s certainly more to be unleashed – particularly when it’s combined with other power adders such as intakes, exhaust, cams, or forced induction.
It's one of just five built in total.
Interest-free financing and more on compact luxury crossover.
Another carbon part for the newest pony car.
A pretty cool tailgating rig, we'd say.
It's unclear what those export markets will consist of.
It didn't top every category, but was the best all-around.

That's about the same a 3rd gen gets from a 93oct tune. I'm still not sure what benefit this 4th Gen has over 3rd gen unless you're wanting to make like 1200+HP, which is pretty unusable on the street and more than most can afford to mod to.
At least 1st Gen coyote and 2nd are also separated by a very nice platform and suspension update making a Perf Pkg GT give the previous gen BOSS with its Roadrunner engine a run for its money.
2nd to 3rd was a really unexpected power bump.
3-4...? Not seeing the point. Not only is it still playing catch-up to the Gen 2 specialty car(gt350) in power and track performance, it doesn't even significantly beat the Gen 3 GT/Mach1. It's a driver's race as proven by multiple reviewers, tests track results. The S650 is only significant for having huge LCD screens.
@19Bullit, clearly you haven't spent much time in, under, or around an S650. The braking systems are entirely different, rear suspension, magneride, intake system, cooling mods, interior, and I can go on and on. But it's okay, most of us are here to support this new Mustang and the benefits tuning will deliver.
