From their website: "PR-X, also known as Performance Race Xtreme, is our top-performance tune for the 2017 Ecoboost Trucks. This is by far the preferred tune on this truck due to the ridiculous power gains over stock. The truck feels so much lighter with the increased throttle response and part throttle boost. Wide open throttle boost is increased over stock by +/- 15% which equals out to around 3/5 psi, depending on the rpm. Peak boost is around 20psi +/-. "
