p307 made from 2001 till 2003 have Valeo bsi with 912, and Sageme dash with upd780973, and software in dash who let to reset milage with power up dash. From 2003 p307 have Valeo bsi with 95160 and same Sageme dash with same upd780973 but newest sw, and cant been reseted without programing!
But cars have made in the end 2002 and in the start of 2003 have "new" bsi but "old" type of dash, so some cars can been done BSI onlly.
Its not worth to try do bsi onlly in cars after 2003! Beter charge customer for morer money and program dash and bsi at once! I am 100% shure, becouse have bad experience when milage jumping back, and must program bsi again, and do dash!
