Hi Brunno!
If you have a custom tune already I would contact your tuner.
If you are running one of our off the shelf maps I'd recommend reaching out to a Protuner to get a map that will work with your EVT 775 kit. Many of our Protuners are very capable of remote tuning.
It looks like you are in Brazil and the pump fuel there is generally 25% ethanol and 75% gasoline which may account for some of the discrepancy. However I'd more expect a system too lean code than rich.
Generally a system too rich/lean code is brought on by the long term fuel trim corrections hitting a preset limit in the ecu causing it to illuminate the check engine light.
Out of curiosity have you checked your fuel pressure regulator vacuum reference line? If this comes off you will have a vacuum/boost leak but will also be running higher fuel pressure at idle and lower fuel pressure under boost.
