The reason 87 works ok is that the PCM will retard the timing to avoid ping or
Pre detonation. That's why it is acceptable, the PCM will recognize it and adjust.
Please note that your performance does suffer slightly. Another thing to note is that if you can actually hear
Ping or knock you may have a much larger issue, just a heads up. Could be knock retard which is not good. lol
Can I get an amen?
