Frequently asked

Ford and Lincoln, on PCMTec. Every platform we have developed is listed with its price on the recalibrations page.

If yours is not there, send the year, model, engine, transmission and strategy code to customer support and we will tell you where it stands.

A recalibration is $400 on a manual and $600 on an automatic, because automatics include transmission recalibration. The GT500 with its DCT is $500.

Custom OS adds $600 on any platform.

Factory calibrations are designed for the widest range of drivers and conditions. Comfort, efficiency and long-term reliability in commuter use come first, so the engine and transmission strategies often lean toward higher slip, softened torque transitions and aggressive power reduction as charge temperatures rise. Those choices suit daily drivers, but they limit precision and consistency once you ask more of the vehicle.

We work with OEM-level access, recalibrating the engine, and the transmission on automatics, to perform with greater accuracy under higher loads while preserving the protections that keep your powertrain safe.

Transmission recalibration

• Converter and clutch strategies are optimized to reduce unnecessary slip, lowering friction and heat while improving torque-holding capacity. That improves reliability under load and reduces parasitic losses, so power delivery feels more direct.
• Shift execution is sharpened for faster, more predictable gear changes under load, with carefully profiled pressure curves to avoid harshness at light throttle.
• Adaptive learning and KAM, the keep alive memory where the PCM stores what it has learned, are re-aligned for higher torque, so the transmission keeps adapting intelligently instead of mislearning at elevated power.
• Torque truncation and spark cut events are recalibrated for precision, balancing component protection with minimal interruption to acceleration. That keeps the connected feel while still managing stress on clutches and shafts.

Why smooth shifts aren’t always better →

Engine recalibration

• Airflow, torque and fueling models are recalibrated from the ground up, so torque delivery is precise and consistent with how the engine actually behaves, rather than capped or scaled estimates.
• Torque management is kept and tuned for accuracy. Instead of disabling interventions, we restructure spark and air torque reductions to engage progressively and predictably, protecting drivetrain components without robbing forward thrust.
• Charge temperature and density effects are balanced. Power does taper as temperatures rise, but at a measured rate that maintains drivability, guards against detonation and preserves thermal headroom, unlike the abrupt reductions in the factory strategy.
• Fueling and knock strategies are refined to safely maximize cylinder pressure, for consistency every day and headroom for performance use across variable fuel quality and atmospheric conditions.

Our philosophy

Every recalibration we create is deliberate, precise and tailored. Safeties stay in place, consistency is preserved, and the vehicle simply works the way it should: sharper, stronger and more predictable. We don’t cut corners. We don’t copy files. We build them right from the start.

We start by reading out or converting your existing Unleashed tune, to keep the proven elements you already like. From there, we build on it with PCMTec’s full access, using extensive datalogging to tailor everything to your hardware, environment and driving goals.

Your recalibration is built for the fuel you tell us when you order. To switch between ethanol blends without reflashing, Custom OS adds flex fuel support.

The E85 calculator works out the ethanol content of a blend, or how much E85 to add to reach a target.

An optional operating system for your recalibration, controlled from the cruise control buttons and the cluster. It adds on-the-fly switchable maps, launch control or antilag, and flex fuel support.

No. A recalibration is complete without it. How Custom OS works →

Your file can have one of the two, whichever you choose. Launch control does not work from a roll, and antilag is less optimized for a launch. How to use each →

Yes, for the same $600, to any PCMTec recalibration from us.

The fuel, the VIN and the powertrain modifications. If you have them, also the strategy code, your device and, for an SCT X4, its serial. The order form asks for all of it.

OBDX Pro FT and SCT X4. Files arrive as a download and you load them with the device, so the car never needs to come to us.

An OBDX Pro FT logs in PCMTec and can be used on any number of cars. An SCT X4 stays locked to the car it flashes. Both are available from Unleashed Tuning: OBDX Pro FT, SCT X4.

Your order opens a ticket under your email, and an email confirms it. The base file comes next, with instructions for what to log, and revised files follow from your logs until we think the car is right. The whole process →

The base file usually takes 5-7 business days, and each revision 3-5. Messages are usually answered within 3 business days.

Revisions continue until we think the car is right on its current hardware. Seven to ten rounds is normal, and some cars need more.

Load each file with your device, do a KAM reset, drive the car, record a log as the instructions describe, and send it back with a few notes on how the car drives. How each round works →

To send a log, reply to any email about your ticket with the log attached, or upload it on your ticket page. Videos and large files go through the ticket page.

Your account is the email you ordered or wrote to us with. Sign in at Your account with that email and your password, or have a sign-in link emailed to you.

The first time, use the emailed link and agree to the site terms. Then set a password on your account page. Check Remember me to stay signed in on your own device.

Use Forgot password on the sign-in page. A link to set a new one goes to your email and works once, within 30 minutes. Setting a new password signs out every other device.

In Your account. Every file sent to you, and every file you sent, is listed there with your orders and vehicles, and each one is also on its ticket with the messages around it.

Your password is never stored, only a protected fingerprint of it, and a password found in a known data breach is refused. After a few wrong tries, signing in with a password pauses for 15 minutes. If you ever signed in on a device that is not yours, use Sign out on every device on your account page.

The recalibration is reworked for the new hardware as new work, because the file was built for the car as it was.

Revisions for parts bought from Unleashed Tuning are free.

Unleashed Tuning sells tuning devices, power packages, intake, exhaust, fuel and cooling parts for the platforms we recalibrate.

No. Each recalibration is written for one car, so a second car needs its own.

If a dealer update stops the recalibration from working, it can be transferred to the updated PCM for a fee that is less than a new recalibration. Some cases are able to be transferred without the fee. Open a ticket to arrange it.

Yes. We can provide a factory file on request through customer support.

We do not tune any vehicle with emissions equipment removed, and we do not provide recalibrations that disable, bypass, or interfere with emissions control systems. We also do not sell tuning devices or recalibrations for vehicles registered in California.

Beyond that, you are responsible for making sure the configuration you order, and the way you use the vehicle, comply with the rules that apply to you.

A manufacturer or dealer may decline a warranty claim on a recalibrated vehicle. Whether any particular claim is accepted is between you and them, and it is outside our control. We make no promise about how a dealer will treat your vehicle, and we do not reimburse claims that are declined.

We do not charge sales tax outside of Wisconsin.

Depending on where you live, your state or country may have its own tax rules for purchases like this. Your local tax authority can tell you what, if anything, applies.

All sales are final, because each recalibration is custom work for one car. The revisions needed to get it right are part of the order, so if something is off, raise it on your ticket.
