By the way, thank you very much for your advice and comments. Actually, now, I think that Tune is already completely adjusted, the numbers of AFR (14.70) and OAR (-1) are perfect.
Now at night I am scheduled to test the FIST against a GTI MK7 APR stage 2,
so if you can give me some advice you will be welcome, I really want to demonstrate the power of this car
