I agree. I would not have any problem not running a knock sensor on any of my engines. I have not seen any knock retard ever on the stock block in my sig. For 99% of the guys on this board that run 93 octane its a really bad idea.OK MR COMP/ISKY/VP/SUNOCO yeah you need fuel and cam and alot of money but if you what your doing you can get the job done ! I know if I seen a race motor not running a knock sensor it was not the first one around to do that !
