Super Duty runs less power and heavier AdBlue use than the other Next-Gen V6 diesels straight from the factory, so there’s real headroom in a properly built calibration.
On a stock Super Duty we’ve taken a vehicle from 154.6HP/474Nm at the wheels to 206.9HP/552Nm, with the tune built around the strong, reliable torque delivery this chassis needs for heavier work rather than a peak power figure that doesn’t hold up under real load.
As with the other Next-Gen V6s, we recommend the HPD combined transmission cooler and intercooler kit before or alongside tuning to keep intake and trans temps in check under sustained towing.
