factory fuel adjustment

[JAP63]

Ok.
A theoretical question.
If u wound 15 pound into your car and lets forget about cuts and fuel etc for now.which would the car do?
-Would it lean out because of the extra boost....
OR
-Would the factory computer see the extra air and add fuel?

If so it means it is impossible to tune an SAFC by guesswork then..right.?
By mathematically working out extra air percentage and adding the appropriate fuel etc...I know mixtures are best sorted out on a dyno with a probe etc..
But for interests sake..does anyone know?

Factory ECU just dumps fuel until either a) you run out b) injectors run out of flow c) fuel cut.

the afm would meter the extra air being sucked in by the turbo and add more fuel

that said the stock VR4 AFM is pretty easy to max out.

Isn't the max about 280-300hp?

round 380 CFM i think from memory.

2G mas is good for round 658 CFM max

So its not even worth adjusting my fuel maps on an SAFC2 for extra boost?
The factory computer does it for me?

i think not somehow...
