Before Incon was defunct, they had stages as well.  The most popular was 
the 800tti kit (which is what I have).  But they also made some "600HP" 
kits with smaller sized turbos, and also "1100 HP" kits with larger turbos.

Well something is not correct in your tune then.  It IS possible to set it 
up right so that commanded AFR is equal to actual AFR.

That could be.  But what do you think all of the DFI units out there 
use??  Speed Density.

I have to disagree.  There is an enormous amount of information out 
there.  You just have to search for it.  These mail groups are great 
sources of tuning knowledge as well.  I'm not sure why you would need to 
know the exact inner workings of every component.  These people ARE trying 
to make a living selling their product you know.  It's not surprising that 
they don't tell you everything about their hardware, or how to interface it 
with the EEC.  As long as you understand the strategies used, and how to 
tune the car, that's all you need.  Unless you are trying to sell a product 
as well.
