T400 modulators

Red stripe
Dual red stripe
Black stripe
etc etc....these appear to all be adjustable.
So , indicate the design differences please........detailed , not general.
I already realize the differences are tension , apparently.
From most reactive ( responsive ) to least.

Thanks

The diaphram diameters are different on some along with spring pressure. The red and double red were the same diameter if I remember correctly, and the red and black was a little larger in diameter. I don't remember black only. My preference was the red and black. It had a better pressure rise curve but we were at 3600 ft altitude. It will change around with different engines and combos as well.
