    I understand how the EEC uses the MAF data, my question with it, and any
of the other older MAF's designed for the SHO/Mustang that used different
sample tubes for either/or, was always why, when from the factory both were
looking for the same data set.
    All the dyno stuff I've ever seen reported over the years on the list,
etc, was any MAF with different sample tubes (mustang/SHO) always ran better
and made more power when using the "mustang" sample tube.  This always made
sense to me, since both EEC's were looking for the same MAF curve/data
anyway.

I understand trying to run a lower voltage curve (or higher depending on
what you are trying to achieve) but the EEC seems to be sensitive to more
than just injector pulse width based on MAF signal (also spark advance,
etc).  Running nitrous, I'm not sure I'd want to vary too far from a stock
MAF curve.

Didn't some of the SHO guys who hang around NE Dyno (kirk?) test a whole
slew of V6 MAF's sometime?  I thought I remember some C&L units test to?  Do
you have any test results to share?
