HI, I,m currently working on a 1999 4.6 Range Rover with the bosch engine management system. Looking for a company that supplies a supercharger for this vehicle. Found one at "chariots of fire" but they want the vehicle shipped to them for the work. Right now we are doing a computer upgrade from power chip group and a twin tip borla exhaust system. Also a k&n air filter, but would like a cold air induction system if any one knows of one. Thanks for any help that can be provided.
