Thank you I will have to check with my installer and tuner to see which way they are doing it.If you are going to still be using the factory fuel rail pressure sensor (FRPS), then it will display fuel pressure from the OBD2 port. If you are not using it, then you will need to AF sensor, be sure to get the 5v regulator as well.
Yes, the DX rails still use the FRPS is you wish to keep it. If not, we have a block off plate for it.
