Changing spring tension will change mixture, you need a larger 
AFM to be able to flow more.
Think this months issue of Zoom Magazine has an article about it.

IMHO making a MAP to AFM converter is the way to go, but noone
that has done that has posted the schematic.........
Use a MAP IAT, and RPM inputs, bingo.....

 The setup is Bosch L-jetronic in a Lancia Zagato. I do

Yes, it is the same as the 2000

 All components are 81 except the AFM
