Anyone have any tips or thoughts on a supercharger kit for a 04 250sd with the 2 valve 5.4L. Any help would be greatly appreciated.

 

My dad put the saleen 2v kit in his 4.6 grand marquee. We got the kit for $500, including the blown up engine it was bolted onto. We installed it with bigger injectors, NO somputer changes. It ran really rich at everything but WOT (where she purred), and after about 2 weeks of driving, the computer has adjusted part-throttle trim by a lot, and it runs great.
-Hope this helps
