My 2005 F-150 has the 4.6L, and i would like to have a lot more power for towing. After looking a new diesel trucks ive decided to upgrade my truck instead of spending 50,000 for a new one. I have the stx model 4by4 about 78,000 miles. I have been looking hard for a supercharger kit, but cant seem to find one for the 4.6. have any of you ran across a kit for my truck?
