Another interesting thing is 'seat of the pants' (buttometer) vs the
accelerometer.  A richer AFR 'felt' faster - the peaks shown by the
accelerometer *were* higher - BUT - the area under the curve was greater w/
the 12.0 AFR than the 10.8 - higher overall acceleration.  Dunno why, but
I'm going to tune w/ the meter, not my butt or 'theoretical' AFRs.

Yes.

Both sensors post turbo by about 3", in the downpipe.
