New Tuner

Hey guys :slight_smile:
I apologise if this has been covered here already but I have a couple questions.
Firstly I have just started taking the tuning side of this game more seriously and test and fine tune the cars quite extensively before I share them , however it just dawned on me…should I be turning certain options off when tuning, ie - ABS, traction control and so on?
Also because I am new to the tuning and the forza world in general is there a way to get feedback from my tunes? Just so I know that I am not sharing garbage.
Thanks in advance :slight_smile:
