This is the Pro-Tuner version, which means it ships without calibration on purpose. It is aimed at builders who already have a tuner lined up and want to set the fueling and timing themselves rather than run a canned file. The rotor pack is an Eaton TVS 2650 with an integrated intercooler in the housing, so charge temperatures stay controlled on an engine that already leaves the factory supercharged.
