So you have a 3.15 Jackshaft pulley and a 3.00 supercharger pulley? With that combination and the 2.85 serpentine pulley you should be making an additional pound of boost so really you should be seeing 15-16psi without a filter. The filter has shown to drop the boost down by 4psi so you should be seeing close to 12psi with it on. Something is definitely not right. Can you confirm with a caliper the size of your pulleys?
