Unexpected speed in a full-size shell. Our Flex 3.5 EcoBoost calibration enhances torque delivery, sharpens drivability, and refines the 6-speed’s behavior—making this sleeper SUV feel lighter on its feet.

We are able to access and adjust much more than previous softwares allowed, unlocking each platform’s full potential. We now re-calibrate with longevity in mind, including a smoother and more consistent experience across all conditions. Whether you're seeking a more spirited daily drive or laying down repeatable power at the strip, our files retain full use of factory safety systems and drivetrain protection, while improving acceleration, responsiveness, and overall driving engagement. Each file is custom to each individual car, allowing you to get the most out of your vehicle.



The tunes/re-calibrations will be sent as a downloadable file. A base file will be sent, revisions will be logged via the supported devices. Base files may take a few days for delivery.

*Revisions are highly recommended to get the most out of your vehicle for power and reliability.*
