Here's what I found and no one share this I don't know why "dangerous" info.
I spent lot of time to find it out, but finally it's easy.
Hope this will help others.
Here is how to tune Driver Demand Engine:

To complete this, some more info.
For new throttle effective area is needed. For gt500 TB you can find in any GT500 tune, I have also KB stage 2 130mm (attached).
If You don't have it, You have to play, but with method below playing both tables, effective area should be found too.
Ford Racing 62mm per Ford instruction don't need tune, so it works with 4.6 Effective area table (Not GT500), but as Effective area can be left alone, then predicted throttle could be adjusted.
First I thought predicted throttle needs to be copied also, but I was wrong.
This table has to be adjusted after cam installation, turbo, supercharger, wihout it, car will drive good, but could do that better.
Unfortunately it's not possible to do that without SCT logging. Take a look, that X Axis in Predicted throttle is wrong named, this should be ETC Area Opening, not Baro..
Max throttle angle in ETC effective area on X axis must be same value as in last column of predicted area and vice versa (as You can see this in stock tune). Max angle You can log, GT500 for eg has not 82 max angle.
I attached also SCT histo for log.
You need to log Effective area by ETC for X, ETC Manifold vacuum for Y and wheel torque error.
Goal is to get wheel tq error close to zero and IPC sum to low values. After it's done, You can set wheel tq error max to normal values.
Easy check if throttle is good calibrated is to slowly increase RPMS on idle, if You can stop every 100rpm, then it's probably good. If You can't hold or quick adjust RPM's You want, then it's wrong.
Now it's time for speed density and transmission... Best to know is why, not what to set...
Hope finally all information for FORD will be complete and users will share more, like GM comunity...
