i am going to use this product in my 92sc,i have done all my other cars,with GREAT results,but none are supercharged..........has anyone used this product,and did they intoduce it thru the supercharger or below it,directly into the intake,above the injectors......my castle rep,sounded as if he had little expertise,with sc's and told me to intoduce the chemicals,at the power brake vac. line..........i am not sure i will get the best results, that way in...........any help....len ball
