@Andre_Frazatto If your filament is thermally calibrating using the clips you should not have to change the mechanical settings of the printer unless the XY counter part features are off dimensionally. Increasing the feedrate and lowering the extrusion multiplier will ultimately result in the same output anyway.
If you calibrated properly but are still getting what looks like over extrusion on small details and surface areas I would suspect a part cooling issue or a dwell time issue in a small area. A picture of the results you are getting and your printer hot end would help figure out what direction to head.
A really good part cooling fan and duct or setting the minimum layer time a little higher or printing multiple smaller parts will allow the layers on small areas to cool more before the next layer gets printed and result in much better quality.
Thanks @Jeff_Parish
I actually spent the week working on those calibration pices and the results are alsome!
Never expected my home made printer could get this kind of resolution.
I still have problems on extremely small surface areas, but I agree that it should be a cooling issue.
The first few solid layers are getting a little squishy and fat now (someone called elephant fit). Any suggestions?
@Andre_Frazatto Thank you. Glad they are working out so well for print quality improvements. Post some before and after pictures. Very few people realize what a difference thermally calibrating your filament can make with no mechanical adjustments needed to your printer. Welcome to a whole new level of print quality!
Now on to part cooling. 
Could the part cooling duct below be adapted to fit your machine?
Post a picture of your first few solid layers getting squishy. There could be several things going on. Part cooling might be the solution here again.
@Jeff_Parish Cooling is a problem I was not able to solve completely and/or elegantly hahaha
In Brasil, we use what we can, not what we want 
I’m using a Gred/Wade extruder in a home made Prusa i3.
My hotend is not standard and the nozzles have different sizes. My only solution was this monstrosity so I can adjust the blowing ducts…and my 3D modeling skills are moderate at best.
I tried using some E3D cooling ducts, but as the nozzle size changes, I get cooling the nozzle itself of rubbing the duct on the prints.
I’m trying to take pictures of the other things you asked, but the differences on the calibrations pieces are unnoticeable besides from better finishing on the top and more appropriate overall sizes.
The squish layers are only noticeable by apparently over extrusion (you can see the nozzle makes grooves on the previous layer) and when the print is finished and cooled the bottom (a few layers) is larger than the rest of the print.
