Yes. We tune all Police Interceptor vehicles, including Explorer 2.3L, 3.0L, 3.0L Hybrid, Mustang 2.3L, and F-150 2.7L and 3.5L variants.

Yes. Even though Tow Mode is not a selectable drive mode, it can still be seen and adjusted through tuning.

Yes. We tune both the F150 PowerBoost and 3.0L hybrid Explorer/Aviator platforms including the Aviator GT, Police Interceptor Hybrid, and EU spec Explorer Hybrid.

DMS™ (Drive Mode Specific) is ZFG Racing's proprietary multi-calibration tuning system.

Rather than applying a single calibration to all drive modes, DMS™ assigns different power profiles and tuning characteristics to the vehicle's factory drive modes. Depending on the platform and configuration, drive modes can be calibrated with different power levels, throttle response, transmission behavior, shift schedules, torque management strategies, and other performance characteristics.

This allows customers to switch between different driving experiences using the factory drive mode selector without requiring additional tune flashing.

• Eco: Daily Driver Profile
• Normal: Performance Profile
• Sport: Race profile
Tow: Dedicated towing calibration
• Trail / Baja: Stock Profile

Available drive mode assignments and features vary by platform and application.

Every ZFG Tune is built specifically for your vehicle, modifications, fuel type, and tuning goals.

Your purchase includes:

• Custom ECM calibration
• Custom TCM calibration (where supported)
• Data log review
• Revision support required to complete the tune
• Tune delivery through HP Tuners and TDN

Additional refinements can also be requested after completion if needed.

We offer multiple fuel types, tuning goals, and tuning options. All tunes are custom and will be written for the fuel type, tuning goal, vehicle, and vehicle configuration specified at purchase:

Fuel Type
Fuel availability varies by region, so we generally recommend selecting a tune based on the highest-quality fuel consistently available in your area.
• Auto-Octane (87-93 • Octane + up to E30)
• 91+ Octane (91-93 Octane + up to E30)
• 93 Octane (93 Octane + up to E30)
• E50 (40-60% ethanol content)
• E85 (70-90% ethanol content)

Tuning Goal
This is the starting point for your calibration and tells us what you're looking for in terms of responsiveness, gains, and end-goals:
• Daily Driver (stock-like yet refined)
• Performance (Goldilocks - not too much or too little)
• Race (maximum power and full optimization)
• Tow (towing and high work-demand applications)

Depending on the vehicle platform, you may also have the option of either a Standard Tune or DMS™ (Drive Mode Specific) Calibration, which allows different tuning characteristics to be assigned to the factory drive modes.

The correct option depends on your situation:

Tune Only:
• You already own a compatible device.
• You only need calibration files.

Tuning Package:
• You need both a tuning device and custom calibrations.
• Recommended for most first-time customers.

Additional Tune:
• You already have an active ZFG calibration and need an additional fuel, performance, or other option added to your setup.

If you're unsure which option is right for your vehicle, contact our Sales team before ordering.

In many cases, yes. Existing HP Tuners devices may be used with your vehicle and tuning goals. However, compatibility depends on the specific device model, device generation, vehicle platform, desired tuning method, and tuner preferences.

Not all HP Tuners devices support all vehicles or tuning methods. For example, we may only support tuning via TDN App for some platforms, while others may use VCM Suite. Licensing requirements and existing device usage may also affect compatibility.

If you already own a tuning device, please contact us with the device model and vehicle information before purchase. We will be happy to help determine compatibility and any licensing requirements.

In many cases, an HP Tuners device can be used with multiple vehicles. Generally, these devices can be used to tune multiple vehicles either simultaneously or over the lifetime of the device. However, compatibility depends on the specific device, device generation, vehicle platform, tuner preferences, and licensing requirements.

Most supported vehicles require HP Tuners credits (licenses) before tuning can be performed. The number of credits required varies by vehicle and application. Additional credits may need to be purchased when tuning another vehicle.

Compatibility may also vary based on the model and generation of tuning device being used. Not all devices support all vehicles or vehicle generations, and not all devices support the same tuning methods (e.g., TDN App and/or VCM Suite).

If you are considering using a tuning device on a different vehicle, or using an existing device on your vehicle, please contact us with the device model and vehicle information. We will be happy to help determine compatibility and any licensing requirements before purchase.

Tuning purchases are generally non-transferable and are intended for the original vehicle for which they were ordered. However, we understand that circumstances can change, and requests involving tune or device transfers may be reviewed on a case-by-case basis depending on the specific vehicle, tuning device, purchase history, and requested changes.

In most situations, the original vehicle and tuning device must no longer be associated with the existing tune before any transfer options can be evaluated.

If you are considering transferring a tune or tuning device to another vehicle, please contact us with the details of both vehicles and the tuning device being used so we can review the available options.

HP Tuners offers several advantages compared to many handheld tuning devices. In most cases, diagnostic software, dealer-level diagnostic tools, OBD-based monitoring devices, scan tools, gauges, and other vehicle accessories can continue to be used normally while a tune is installed.

As a best practice, we recommend restoring the stock calibration before performing certain dealer-level programming or software updates, such as Ford FDRS or IDS programming.

Additionally, the HP Tuners Restore file generated from your original stock read is a true and complete copy of your factory calibration and controller data.

Because HP Tuners devices do not permanently marry themselves to the vehicle's ECU, customers generally do not need to worry about long-term device-to-vehicle associations if the tune is removed in the future, such as for resale or returning the vehicle to stock.

Yes. Before tuning with ZFG Racing, any previously used tune or tuning device must be completely disconnected from the vehicle.

For most tuning platforms, this means more than simply restoring the stock calibration. The device must be fully removed or "unmarried" from the vehicle according to the manufacturer's instructions so that neither the tuning device nor the vehicle remains linked to the previous tune.

If you are unsure whether a previous tuning device has been fully removed, please let us know which device was used and we will be glad to help determine the next steps.

Yes. Using your HP Tuners device, you can flash your vehicle back to its original stock calibration at any time.

Many customers choose to return the vehicle to stock temporarily for troubleshooting, dealership visits, or before selling the vehicle.

Returning the vehicle to stock does not delete your custom tune files, and you may reapply your tune later as needed.

Yes. If the dealership performs a PCM software update, your custom tune may be overwritten and replaced with the updated factory calibration.

Not every dealership visit results in a PCM update, but it is possible anytime software updates, recalls, or drivability concerns are addressed.

If your vehicle receives a PCM update, simply contact our team. Depending on the circumstances, an updated stock file and tune revision may be required.

Yes. Our latest Quick Start Guide can be found in our tuning hub: Tuning Central.

No. Thanks to HP Tuners' support for these platforms, we do not currently require ECU swaps or unlock services for any vehicle platforms we support.

Simply read and submit your stock file using your HP Tuners device, and we'll take it from there.

Please note that if your vehicle contains a newly released or previously unidentified operating system (OSID), HP Tuners may first need to add support for that calibration. In those cases, additional definitions may be required before tuning can begin, which can extend the tuning process by up to two weeks.

Drive mode behavior depends on the vehicle platform and the tuning option selected.

Our Standard Tunes provide a single calibration optimized for your selected fuel and vehicle configuration across all drive modes.

The Terrain Management System will still function as intended, according to it's stock "personality."

Even after tuning, Normal and Eco Modes will remain the most relaxed, while Sport and Baja remain the most responsive.

For vehicles equipped with DMS™ (Drive Mode Specific) Tuning, individual drive modes can be calibrated differently. This allows features such as separate power levels, throttle response, transmission behavior, boost targets, and other tuning characteristics to be assigned to different drive modes.

ZFG Tuning is a remote custom tuning service that uses HP Tuners hardware and software.

The ZFG tuning process involves several steps: first, you submit a tune request after pulling your vehicle's stock file using the TDN App. Then, ZFG reviews your request and sends back a baseline tune, which you can further refine through data logging and additional requests until you achieve your desired performance.

Standard Tuning applies a single calibration across all drive modes, optimized for your selected fuel type, tuning goal, and vehicle configuration.

The factory drive mode functionality itself remains intact: Normal and Eco Modes will remain the most relaxed, while Sport and Baja remain the most responsive.

Where applicable, DMS™ (Drive Mode Specific) Tuning allows multiple calibrations to be integrated into the factory drive modes, enabling different power levels, transmission behavior, and vehicle characteristics without requiring additional flashing between calibrations.

DMS™ provides greater flexibility while maintaining factory-style operation, though it is only supported for 2020-2024 Ford Explorer and Lincoln Aviator 3.0L Platforms at this time.

There's no limit. However many are needed to complete your tune are included with purchase.
You can also request refinement post-completion if needed.

When we say "complete," it means our tuner has determined there are no opportunities for further improvements based on your data logs, tuning goal, fuel type, etc.

What this does not mean: No further changes can be made.

You can request refinements anytime, including adjustments based on your experience over time.

Yes. All ZFG Tunes include custom calibration for the engine (ECM) and transmission (TCM).
We don't write ECM- or TCM-only tunes.

The price you see is the price you pay for a full, custom tune.

What's the difference between a custom tune and off the shelf tune (OTS)?
Custom Tuning: Custom tuning creates a personalized tune based on your personal goals, preferences, and feedback, as well as your vehicle's specific setup and modifications. Custom tunes are written and refined over time rather than being "one and done." This approach offers the most precise adjustments available, resulting in the best performance and increased customer satisfaction.
We work very hard to make sure customers get the power and driving characteristics they are looking in each of our custom tunes.


Off-The-Shelf (OTS) Tuning: OTS tunes are pre-configured, "one size fits all" tunes. They are written with the intention of being generic and broadly compatible, based on what's been tested on one vehicle. OTS tunes may not fully optimize performance due to their nonspecific nature.

It depends, but most customers complete the tuning process within approximately two weeks of submitting their stock file.

The largest factor is turnaround time between revisions. Customers who submit logs and feedback promptly typically complete the process faster, while delays in log submission will naturally extend the overall timeline.
