Well the bit about them developing the kit before Mountune/Roush/whoever is true because when I went to Janspeed back in 2005 they told us they had indeed been approached by Ford to develop approved tuning packages that included induction kits, exhausts and remapping. Like you say though Azz, Ford didnt go with them for whatever reason..
Sorry Dal but Roush did buy Mountune out... 1/7/04 Industry news... "Roush buys renowned race engine builder from UK.."
