If by no-brainer, you mean for use by people without brains, then I agree.
That mass-flo set-up has to be about the worst set-up for a lumpy idle cam.
Mass air sensor is very sensitive to placement and that set up looked bad.
It may not matter if you run an "EFI cam" with wide lobe centers but but
big port and big inch Clevelands like narrow lobe centers. The mass air
sensor doesn't know the direction of flow so will respond to reversion
flow as if it were induction flow. Anyt sort of overlap in that cam and
you'll confuse the sensor. Moving the sensor farther away helps but there
are limitations. The Mass-Flo guys claim you never have to tune their
system which is a lie since they use an A9L EEC-IV. There's a reason things
like the EEC Tuner, TwEEcer and PMS exist.

I agree with Dan on this one. We had a 5.0 Mustang in the shop not that long ago with a stroker motor and lumpy cam. It took us ages to get the idle right not to mention cold start and such. Tweecer and such help but I will take a good MAP based aftermarket ECU over the stock MAF one any day.
