well i measured my lower crank pulley and it measures a little over 9". so with the stock supercharger pulley 3.65" looks like im running about 12.9 psi of boost based on this website http://www.stangshiftergaskets.com/2...m#_Toc35092344 so it looks like i may need a dyno tune to make sure my a/f ratio is okay. is there a way to tell if my car has been tuned for the lower crank pulley??????????????
