OK i tried it and... I am limited for max 55mg of fuel but i want 62, I make a log and it looks like MAF limiting me. In stock soft were in smoke map maximum MAF 900mg, I extended it for 1050 because i want 62mg. But i still have only 940mg of air :( Turbo is increased from 1bar to 1,1 bar and i am afraid of more increasing boost. I try to buy new air filter but i dont believe it. Some other ideas guys? I really need to increase boost more?

I will give you some general tips for remap this car.
You can increase boost with 200 mbar (0.2 bar) without problem.
You can go with AFR 16.5, that means for 62 mg of fuel you need 1025 mg air, you can edit your X axis.
Your maps are in mm3 right? How you converted mm3 to mg if you say 62 mg ? This means ~75 mm3
Maybe you have a used old MAF, for 2 bar pressure in the engine, you should have ~1000 mg/stroke air, but not 900 as you said that is stock. Old MAF can have a bad influence on air readings

About SOI timing, you can add let's say 2 degrees without problems. Anyway there should be SOI limiter which has still safe values. Even if you try to add 10 degrees to SOI, the soi limiter will not let you to damage the engine if you don't touch it.

Thank you very much for help :) I converted mm3 into mg with factor 0,835. About MAF sensor i try to clean it with some spray cleaner, and if it dont help, i will buy new. Air filter will be new too. And i changed soi limiter little :? but really little. Thank you for reply :)
