If you have the possibity to see the AFR you shuld change the injectors to smaller ones, or reduce the fuel pressure. Or buy a greddy emanage

I've heard many bad opinions, but never explanation why about the SAFC, so I'm trying to understand your post.
But it is difficult to me to see the connection you are doing between "lean the mixture" and "the stock ecu will give the ignition later".
To have feedback from the mixture, you need to have 02 sensor, which we dont ?

But then you are saying it: "The ECU has an igniton table for different loads and different RPM. ". Which is true.
The maps are RPM/Load based and not connected to the mixture.
