Well, it seems like you’re doing OK in two out of three situations (wet & sim vs dry), and based on what you said about how the kart feels (and how it looks)… and also based on @tankyx’s experience/advice, I would start by dialing some oversteer/rotation out of your chassis and see if that allows you to build confidence in the entry and rotation phase so you can carry more speed in, and get on the gas sooner.
I’m more of a ‘driving specialist’ than a chassis guy, so the thread below might be helpful. If you have other setup questions that are not covered there, I’m sure someone will jump in and help out.
Good luck!
