I take "tuner output" to mean this is either amplified RF or IF from the mixer. It has to be one or the other if you are going to send it to an FM detector.
Whatever it is, it's not the constant high level local oscillator output. You need to measure the local oscillator frequency and subtract 455 kHz from that to calculate the station frequency you are tuned to.
