I have a procharger with the 11psi pulley. It made 11psi before it went to the shop. I got p+p heads and intakes and 1.73 rr. The dyno guy said it made like 15psi at 6k on the dyno. Did someone put something back to gether wronge. Also i would like to mention that my procherger has been leeking oil. Would a low amount of oil alow the procharger to move more freely therefore push more air. I was just of the understanding it was to make less boost now. Any comments would be great
