Also, what do you think about overall timing? I feel really big drop of torque in low rpm range and whole timing doesn't even reach stock values...
You have zero timing correction at peak load. Increase requested timing until you see some correction.
And one last question: If you open my csv log, you'll see that my requested engine load is never reached by actual load, but boost reaches calculated values (190 torque = 1200mbar of boost). Actual load hardly reaches 180. Is this normal?
Its only not normal if your actual is *really* far off, which it doesn't appear to be.
If your intake setup is stock, don't worry about it.
If not, you could raise your g/sec a bit if you like. be advised, though, if you change load around, all sorts of things might change, and you might have to start tuning from scratch (particularly fueling and timing)
