Absolutely. Drag the significant other out for you WOT 
runs. "Ok, hold this voltememter in your lap. If it 
drops below 0.75 volts shout 'lean'". Watch the 
exhaust. If it's black, shout 'rich'" As i shift, watch 
the boost gauge. Take note of peak boost for each gear 
and at what rpm it occurred in each gear. Watch for 
boost spikes and taper. Oh and put these headphones on, 
they're clipped to the head so you can listen for any 
pinging. Thanks hon". Lol. Can't you just see the 
confused, sour look on her face? ahahaha. But yeah 
assistants are good.

8.7:1 and 9psi on 93 ought to be fine assuming decent 
mixtures and no drastic changes to squish height or 
quench area assuming you have an IC. Could be 
borderline non-intercooled though.
