Got questions about tuning your Mustang, F-150, Bronco, or other Ford vehicle? Whether you're new to tuning or just want the latest info, we've compiled everything you need to know right here.
If you've added performance parts like an intake, exhaust, supercharger, or nitrous, your factory tune won't keep up. A custom tune optimizes fueling, timing, and drivability for your exact setup—helping you make more power safely and reliably.
Most tuners offer free standard revisions for a limited time. Here’s how some of our top tuners handle it:
It depends on the dealership. Some will flag your ECU as modified even if you return it to stock. Others may be more lenient. Always check with your service advisor before tuning.
The best tuning device depends on your platform, tuner preference, and desired features:
Yes, as long as it’s not locked to another vehicle and your tuner supports that device type. Be sure to confirm with your tuner before purchasing a tune.

Yes. All supported devices will automatically save a copy of your factory tune before flashing a new one. This lets you revert to stock at any time.
Each tuning device includes a "Return to Stock" function. You’ll find the option in the main menu. Refer to the guides below for step-by-step instructions:
Use the tuner’s software to check for updates:
Remote tuning is the process of sending datalogs and receiving updated tune files from your tuner via email or through the TDN app. You’ll perform pulls or drive cycles, log the data, and send it back for revision.
The Tune Delivery Network (TDN) by HP Tuners is a mobile platform that connects you with your tuner. You can receive tunes, send datalogs, scan for codes, and more—all from your phone.
To connect with a tuner in the TDN app, you’ll need their unique invite code. Enter it in the app to gain access to tune file transfers and logs.
*Codes may vary based on order or tuner workflow
No. All tuners we work with adhere to EPA guidelines. That means they will not disable emissions-related components or turn off warning lights related to them.
If you change major parts like injectors, throttle bodies, or add boost, you’ll likely need a new tune. Minor bolt-ons may qualify for a revision—check with your tuner.
Most tuners send your initial tune within 1–3 business days after receiving your completed tuning form. Delays may occur if the form is incomplete or you're slow to reply to emails.
Always include your full mod list, fuel type (octane or E85), driving style (street, track, drag), and any known mechanical issues. The more info your tuner has, the better.
Yes, but you may need to reset or unlock your device, and you might require additional HP Tuners credits or a new license. Make sure your device is compatible with your new tuner.
No, but it’s recommended—especially for forced induction or high horsepower builds. A wideband lets you monitor air/fuel ratios accurately and can help with datalogging.
Yes—if you're using the RTD4 or any device that works with the HP Tuners TDN app. Devices like SCT X4 or BDX require a laptop and LiveLink software for datalogging.
You must use the exact fuel type the tune was built for—91, 93, or E85. Using the wrong fuel can cause serious performance issues or damage.
