Ford has added a variety of performance calibrations to its catalog in recent times, giving owners of various Blue Oval models the chance to unlock some extra power without voiding the factory warranty. Those include the Ford Ranger and its turbocharged 2.3L I-4 EcoBoost engine, giving that combination a boost of 45 horsepower and 60 pound-feet of torque over the stock ratings of 270 horsepower and 310-pound-feet. Now, the newly-released 2024 Ford Mustang EcoBoost calibration takes the same engine even further up the power band, moving it far past the old High Performance Pack, too.
The new S650-generation Ford Mustang EcoBoost calibration is listed in the Ford Performance catalog under part number M-9603-M4D, with a retail price of $850. It takes the 2.3L EcoBoost’s output up from the stock ratings of 315 horsepower and 350 pound-feet of torque to 350 and 400, respectively, which are gains of 35 horsepower and 50 pound-feet. That gets the EcoBoost pony car a bit closer to the V8-powered GT – at least in terms of torque – as it churns out 480 horsepower and 415 pound-feet (or 418 with the optional active exhaust), too.
In addition to that power boost, the 2024 Ford Mustang EcoBoost calibration also reportedly improves throttle response throughout the rev range, though it does require premium fuel with a minimum octane rating of 91. It is 50-state CARB legal, however, and comes with a three-year, 36,000-mile Ford Performance Parts warranty that kicks in at the vehicle’s in-service date, but only when installed by a Ford dealer or an ASE/Red Seal certified technician.
Like all newer Ford Performance calibrations, this one comes with the ProCal 4 tool needed to install the tune, though that part is VIN-locked, so it can’t be used on other vehicles. This particular calibration only works for U.S. and Canada-based vehicles, too.
It’s certainly possible that we could see this same calibration – or one like it – offered as standard equipment on the forthcoming S650 Ford Mustang EcoBoost RTR model, which hasn’t yet been revealed – though that’s set to happen on October 15th, 2025, at Race Service in Los Angeles, California.
Largely due to its vertical integration.
Nationwide lease and cash back on the off-roading SUV.
How far it's come since the early days.
Though it has 650 supercharged horsepower.
And the potential weakening of emissions rules.
That site is going to grow yet again very soon.

Does it have a wet-belt like other eco-boosts? If so dump that trash
Tunes don't have belts.
But if you're possibly ill-formed question is in reference to the 2.3EB in the Mustang, that particular engine utilises a timing chain and not a timing belt, wet or otherwise.
Hmm maybe one day they’ll position the 4 banger above the 8 like they did to their v6…. Naw but this is a worthwhile tune, and being under warranty seems like it’s totally worth the $850
Yeah, all 2 and 2.3 have a crank gear driving thrill.
Obviously can't be production due to fuel economy impact......I've seen that engine go to 800 h.p. but, how long do u want it to last, can it pass emissions, and impact on the fleet mpg as cars are binned different than trucks and last I checked, not a lot of Ford cars to help balance the numbers (like a low volume or aftermarket authorized, not production so doesn't count as long as the # stays below the threashold).
But how does it sound? The V8 has an unmistakable sound when the exhaust pounds the air. I'm thinking the 4 cyl might fall short.
I mean when buying the EB for thousands less than a GT, I'm not sure the owner would care much
When the engine blows at 36,001 everyone cares.
Most likely have 3 to 4 years of payments left!
Maybe more if you need an 84 to 96 month loan.
Eco-Crap engines are 1 owner cars if they last that long
The turbo 2.3 will last a long time it is a tired and true engine. The new Ecoboost 3.5 has been refined to a point its Ford most reliable engine left in stock tune. My brothers 3.5 ecoboost has over 350,000 miles and still going strong not one thing has failed and now his son is driving it. He bought another new F150 with the 3.5 and loves it too. The F150 5.0 now has a wet belt for the oil pump and variable displacement junk that's on the new 5.0 truck engine. The Mustang's 5.0 has neither the wet belt or the variable junk. Why Ford messed with a good engine and probably made it a bad engine now is beyond me. If Ford reads this site give me a Ruby Red Ranger Raptor, please for 2026 hate all your flat colors of different shades of gray and tan.
