this is a supercharged car with autolite 0 plugs factory coils and checked fuel pressure and found running low so replaced pump with shelby gt 500 pumps and harness and the car giving a code for several cylinders and replaced them coils but still have a miss anyone got any ideas
 
This is the SN95 4.6 forum so you might get more responses in a more appropriate forum. But your question sort of trancends the valve count so:

You say the fuel pressure was found to be low and that the car has a blower. The question that naturally comes to mind is "was there damage done by running low fuel pressure on a blower car?"

Did you hear detonation?

Have you checked the compression?
