Add Custom Tuning
What is a lifetime tuning package? Lifetime tuning gives you free retunes for part changes after you’ve started tuning. No matter how many parts you change on your car you will continue to receive revisions free of charge. The only exception to this is tuning for the addition of an aux fuel kit or any other controller that requires programming
With the Standard Tuning package you will get a custom tune, and revisions only for the modifications you currently have on the car. Any subsequent mods after the tuning process has started will result in a retune fee of $100. If you change engines or turbochargers you will be required to purchase a new tune.
Tuning Device (RTD4)
The HP Tuners RTD4 + Credits is the latest-generation OBD-II interface built for enthusiasts and professionals looking to unlock their vehicle’s full tuning potential. Designed for use with the HP Tuners TDN app or VCM Suite, the RTD4 allows you to read, write, and log your vehicle’s ECU and TCM data with faster flash times, enhanced storage, and improved connectivity. You’ll need the RTD4 to communicate between your vehicle’s computer and your tuner, enabling precise calibration adjustments for power, drivability, and performance. Once connected to your vehicle’s OBD-II port, the RTD4 works seamlessly with your custom tune file—delivering real-time data logging, diagnostics, and flashing capabilities all through your smartphone, tablet, or laptop.
Add Tune Add-On
Aggressive exhaust "pops and bangs" when you’re in neutral or decelerating. Activated between ~3,500-4,800 RPM, it works best with a full aftermarket exhaust but still adds character when using factory components.
Add Intercooler
The CVF + EMS S650 Race Intercooler is a must-have upgrade for any 2024-2025 Ford Mustang EcoBoost S650 owner looking to take performance seriously. Engineered with computer-modeled cast end tanks (rather than simple welded aluminum), this intercooler supports significantly better airflow and heat dissipation—offering over 200% more core volume than the stock unit.
Choose Air Filter
An easy and effective upgrade for anyone looking to improve airflow and overall performance. Designed as a direct drop-in replacement for the factory filter, it allows your turbocharged 2.3L engine to breathe easier with less restriction, helping reduce turbo lag and improve throttle response. You’ll want this upgrade if you’re tuning, adding bolt-ons, or simply want a smoother, more efficient setup. It works by filtering out dirt and debris while increasing the volume of clean air entering the engine resulting in better performance, improved efficiency, and a more responsive driving feel.
Choose Intake
One of the easiest and most noticeable upgrades you can make. It replaces the stock air-path with a smoother, larger diameter tube and low-restriction filter so your 2.3L turbo engine can breathe freer and pull in cooler, denser air. You’ll want this if you’re already running mods or just want better throttle response and a more engaged driving feel. It works by reducing “choked” or hot under-hood air, giving your engine more oxygen with each intake stroke which helps it spool faster, respond quicker, and generally feel more alive.
Choose Downpipe
The 3-inch Stainless Steel Catted Downpipe is a simple but powerful upgrade for your 2024–2025 Mustang EcoBoost. It replaces the factory pipe that connects your turbo to the exhaust, allowing the engine to breathe better and push exhaust gases out more efficiently. Built from high-quality stainless steel, it’s stronger, smoother, and flows much better than stock, which helps your turbo spool quicker and gives the car more power and a deeper tone. You’d want this if you’re adding other performance parts or just want your Mustang to feel more responsive. It’s a direct bolt-on part, meaning it fits right in place of the original and doesn’t require major modifications.
Choose Exhaust
A smart upgrade if you’re looking to give your Mustang just that little extra growl, improved flow, and a bit more character. It replaces the heavy, somewhat restrictive factory components with smoother tubing and better construction—so your turbocharged 2.3L engine doesn’t have to fight to push its exhaust out. You’ll want this if you’ve done other performance mods or simply want your car to feel more alive: sharper throttle-response, a more aggressive tone, and a more refined driving experience. It works by reducing back-pressure and improving the volume and speed at which exhaust gases exit, so the engine can breathe better and run freer.
Choose Suspension
Looking to tighten up your ride, sharpen the handling, and just feel more connected behind the wheel? You’ll want this upgrade if you’re adding power, go to the track, or simply want your car to handle as good as it looks. It works by improving chassis stiffness, reducing unwanted motion, and keeping the tires planted and the suspension in control instead of letting the car lean or hop around.
Add Suspension Components
These kits replace or reinforce the factory components with stronger bushings, adjustable springs or dampers, and better sway bars so your Mustang doesn’t wobble in the corners, squat under acceleration, or feel floaty on the highway.
Add a Catch Can
a smart little add-on if you’re running your turbo engine hard or tuning it for better performance. What it does is catch the oil-laden vapors that naturally build up in the crankcase ventilation system before they get re-introduced into your intake, this helps keep your intake tract, throttle body and intercooler cleaner and the engine running smoother for longer. You’ll want this because cleaner air-paths mean better tuning potential, more consistent performance and fewer annoying carbon or oil deposits down the line. It installs pretty simply, usually in a location under the hood, and once it’s in place it quietly does its job without any fuss.
Exterior Styling
Giving your ride that show-worthy finish without messing with the engine. From rear deck-lid spoilers and rocker-splitter kits to upper grilles with LED accents and windshield banners, this lineup lets you totally refresh the look of your Mustang. You’ll want it if you’re upgrading performance parts or simply want your car to turn even more heads. It works by replacing or complementing factory exterior pieces with higher-quality, more aggressive-looking components that bolt on easily, so you get great looks, improved presence, and a strong “finished” feel without heavy install hassle.
