Added 10%, then another 10%, no changes.

Ended swaping for stock VE ECU and the problem persist so the issue is not there, is something else.

I'll need to start testing to see what it is... I'm suspecting fuel pressure, MAF or oxygen sensor issues (it leans out), any thoughts?

(problem is now also happening when fully warmed up but to a less extent).

I had a broken oxygen sensor, replaced it and problem went away.

The only issue that remained is that it leans out when using any value above 182..
