Those plugs might be better for you because you are supercharged. But, they will not give you 30 horsepower. Maybe if that Mustang was running a 300 shot of N20 and a supercharger, with stock plugs running a HUGE gap because they were worn, then yes...maybe he gained some horsepower because it was missing and sputtering like crazy with the stock ones that were shot.
Use your common sense. Even a 300 dollar MSD which optimizes spark and multiplies the number of sparks on each cycle doesn't give you crazy amounts of horsepower. It simply optimizes the efficiency of a highly tuned engine that makes lots of power.
