The more "stable" it is, the less accurate it is.

wcs: torque curve looks awesome but it's a bit low.
Maybe you should run synthetic oil, that should help you out quite a bit.

What does a stock graph look like and what is the significance of the accordion tube in the stock set up

the accordion tube is just a flexible coupling.

Could the ripple in the tube be a factor in the design or has Mazda needed to add two extra screens in the flexible duct to overcome the problems caused by the ripples.

I guess Mazda was keen t us plastic to minimise heat soak associated with the use of metal

Though that is true, I don't think it has really been discussed anywhere in depth, so the poster's misunderstanding can be excused.

ripples in the intact track are never a good thing. You have to think of the inside of the intake ( from filter to combustion chamber) like streamlining. A lot of the the same principles apply.
Ripples in an intake will always be a cause of restriction and increased turbulence.

I wouldn't say "always", but that is the principle.
That said, the inside diameter of the inner "ridges" of the accordion tube are slightly larger than the TB inlet, so its effect is completely negligible.

The accordion ID is larger than the 3.5" OD of the main MAF tube, the TB inlet OD is 80mm (3.15"), and I would guess that the actual butterfly plate is probably less than 3" ID (never bothered to actually measure it)

so yeah, what he said ...
