Your Ford Maverick EcoBoost is already one of the more surprising performance values in the compact truck segment — and Ford Custom Garage just made it significantly more interesting. The Ford Maverick 300T project vehicle, debuted at SEMA 2025, gives EcoBoost owners a factory-adjacent pathway to 300 horsepower and meaningful torque gains without touching the engine block. The retail package — the SV300T pack — carries a price of $5,000.
Stock Baseline: What the 2026 EcoBoost Actually Gives You
Before deciding whether $5,000 is worth spending, you need an honest picture of where you’re starting. The 2026 Ford Maverick EcoBoost produces 250 horsepower and 280 lb-ft of torque from its 2.0L turbocharged four-cylinder. In a truck that weighs under 3,500 pounds, those are already competitive numbers. The alternative powertrain — a 191-horsepower hybrid — is a genuinely good efficiency choice, but it is a different vehicle for a different driver. If you’re reading this, you either already chose performance over maximum mpg or you’re actively deciding between the two.
The EcoBoost platform makes a credible tuning candidate for a specific reason: Ford’s 2.0L architecture shares engineering DNA with a broader performance ecosystem inside the company. That relationship is exactly why Ford Custom Garage could approach this as a structured development program rather than an improvised modification. The technical foundation was always there.
What Ford Custom Garage Actually Changed
The headline hardware change is a turbocharger swap. The 300T replaces the stock unit with the larger turbocharger from the 2.3L Mustang EcoBoost engine. That single component does most of the heavy lifting on output numbers. The SEMA 2025 project vehicle demonstrated 300 horsepower and 317 lb-ft of torque — gains of 50 hp and 37 lb-ft over stock. The retail SV300T pack claims 300 horsepower and 350 lb-ft of torque, representing a 70 lb-ft torque improvement over the stock figure.
The Mustang EcoBoost turbocharger is not an unproven piece of hardware. It carries real-world mileage behind it in a performance context, which gives the swap a reliability baseline that a generic third-party tune cannot credibly claim. Ford Custom Garage’s involvement means engineering oversight behind the calibration — not just an ECU flash accompanied by a warranty disclaimer.
One number worth clarifying before purchase: torque. The 300T project vehicle is documented at 317 lb-ft, while the SV300T retail pack claims 350 lb-ft. Reporting on the Maverick 300 horsepower upgrade pathway associates both figures with different stages or configurations of the program. Before committing, confirm the specific torque output for your exact package in writing from your dealer or Ford Custom Garage directly.
Specs Comparison: Stock vs. 300T Project Vehicle vs. SV300T Pack
The table below gives you a direct side-by-side breakdown. Torque figures may vary depending on final tune configuration — confirm specifications with Ford Custom Garage or your dealer before purchase.
| Specification | Stock 2026 EcoBoost | 300T Project Vehicle | SV300T Pack (Claimed) |
|---|---|---|---|
| Powertrain | 2.0L EcoBoost Turbo | 2.0L + Mustang Turbo | 2.0L + Mustang Turbo |
| Horsepower | 250 hp | 300 hp | 300 hp |
| Torque | 280 lb-ft | 317 lb-ft | 350 lb-ft |
| HP Gain Over Stock | — | +50 hp | +50 hp |
| Torque Gain Over Stock | — | +37 lb-ft | +70 lb-ft |
| Upgrade Cost | $0 | N/A (project vehicle) | $5,000 |
The hybrid powertrain produces 191 hp and has no performance upgrade pathway of this kind. The EcoBoost is the only route into this conversation.
On pure math, the SV300T pack works out to $100 per additional horsepower. In the performance aftermarket, that is a competitive number — particularly when the source is a Ford-developed program with documented engineering oversight rather than an anonymous online calibration.
Trade-Offs You Need to Understand Before You Pay $5,000
The upgrade is compelling. The trade-offs are real. Think through each of these honestly before committing.
- Warranty exposure. Any powertrain modification can affect factory warranty coverage. That is a contractual reality, not a scare tactic. Have the warranty conversation with your dealer before installation and get the answer in writing. Ask specifically whether the SV300T pack is installed and supported as a Ford-backed accessory or whether it creates coverage gaps for related components.
- Drivetrain stress. The Mustang EcoBoost turbocharger is a proven unit, but running higher boost and torque through the stock transmission, driveshaft, and axles means those components operate closer to their design limits. Longevity depends heavily on how you use the truck. Spirited daily driving is a fundamentally different load than consistent hard launches or track use.
- Fuel consumption. The upgrade does not improve efficiency — it increases output. Under hard use, fuel consumption will rise. If maximizing mpg is your primary objective, the hybrid is the correct choice. EcoBoost owners have already accepted that trade-off; 300 hp simply makes it more pronounced.
- All-in installation cost. The $5,000 price is for the SV300T pack itself. If dealer installation is not included, that cost is separate. Ask explicitly what the complete installed price looks like and whether Ford Custom Garage calibration support is bundled or billed additionally. Do not assume the sticker price is the final number.
Who This Upgrade Actually Makes Sense For
The strongest candidate for the 300T path is an EcoBoost Maverick owner who uses the truck as a daily driver and wants legitimate performance credentials without committing to a full engine build. The result is a sub-3,500-pound truck with 300 horsepower and a Ford-developed calibration. Early drive impressions describe the upgraded Maverick as feeling like a hot hatch — a characterization that makes sense given the power-to-weight math.
If you tow near the Maverick’s rated capacity with any regularity, the torque gain is functional, not cosmetic. The difference between 280 lb-ft and 317 to 350 lb-ft is something you will feel pulling a loaded trailer up a grade. That is a practical argument, not just a spec sheet improvement.
If the horsepower gap was your primary hesitation when cross-shopping the Maverick against more powerful compact trucks, $5,000 closes a meaningful portion of that gap without moving to a heavier, less agile platform. That is a credible competitive answer that did not exist before SEMA 2025.
If you bought the hybrid or are still choosing between powertrains, this upgrade is EcoBoost-exclusive. The hybrid’s architecture does not support this kind of modification. That is a concrete factor to weigh if performance headroom matters to you down the road.
Bottom Line: Is the $5,000 SV300T Pack Worth It?
The math is competitive. Fifty additional horsepower, meaningful torque gains, a Mustang-sourced turbocharger with a documented performance history, and Ford Custom Garage engineering oversight — for $5,000. In the performance upgrade market, that is a reasonable price for what you are getting, particularly when the alternative is assembling third-party components with no factory involvement or accountability.
The credibility factor carries real weight. A SEMA debut and Ford Custom Garage backing are not guarantees of bulletproof long-term reliability, but they represent a meaningfully higher level of engineering accountability than an ECU flash purchased from an online forum. The Maverick 300T’s SEMA showcase put real output numbers on real hardware in front of the automotive industry — that is a different statement than a claimed dyno figure from an anonymous tuner.
The honest caveats remain: warranty implications and long-term drivetrain stress are legitimate considerations, not hypothetical ones. Get clear written answers from your dealer before you commit. Confirm the torque figure specific to your configuration — 317 lb-ft or 350 lb-ft — because that gap is material and worth clarifying in advance.
If you want 300 horsepower in a compact truck, you are prepared to pay $5,000 for a factory-adjacent path to get there, and you have resolved the warranty question with your dealer, the Maverick SV300T upgrade is currently the most credible route available. No other program combines this level of output gain with this level of manufacturer involvement in the compact truck segment. The Maverick was already one of the stronger value propositions in its class — the 300T upgrade makes the performance argument substantially harder to dismiss.
