I think the RN is the manufacturer of the chip blanks. I'm not sure how Postons labels there chips, but it looks like your chip is for 30 lb injectors. You'll need a chip for your 40lbers which you could get through Full Throttle, Eric Marshall, or Hartline Performance, all who advertize on this Board.
