The car was tuned on dyno plugged with a headset into the stock detonation sensor. You can hear ANY detonation. If you had a person sitting right next to the engine then the noise in the earphones would be deafening before they could even hear the first sounds of detonation. I am quite satisfied that I dont get any detonation at 24psi and the fuel curves are perfect. There has never been any sign of it on plugs and compression reads 170-175 across all cylinders. No need to start saving just yet I think.
