I am having the absolute hardest time being competitive with a controller online. It seems like I just get left behind by the top 3 or more no matter how hard I push. If I try and push over what I'm used to, I'll either go off track from understeer or spin at the exit of a corner. During qualifying, I am anywhere from 3-6 seconds off pole (GT3 cars, mostly). I'm fairly confident that the guys setting these times are wheel users, based on vehicle movements and spectating races.
I understand that, generally speaking, someone with a wheel and good control is going to be faster than a controller user, but what can I do to close the gap? How much of a difference does vehicle tuning make, and would I able to get by with using the race engineer? I've also been messing with my controller setting and am currently using the one found in Super GT's video.
