43 deg sounds pretty good but that depends on what your able to run , say max TQ mid range at 0 vac " and max boost .
Is it like,around 36@0 vac and 28-30@ boost (this will depend on how much but rough valve).
Generally could might be able to stand 8-10deg of part throttle advance , so in above it be like 45 deg max .
You could maybe make a electronic stethoscope , I have seen a few DIY on it from old electronic parts .
