I find Skyline's tune to be the most stable and would probably run it in the online race, EDK's tune is the wildest ride, and Sutuki's tune with EDK's tranny is for me the fastest.
The right line in sector 2 is crucial, it's got to all flow together, so here's my two cents. The first left, turn 3, I apex at 107mph or more and exit full throttle out to the curbing. I enter 100R mid track accelerating to 122mph. On the fence inside the corner there is a small orange sign, as I pass that marker I lift to 80% throttle as the turn tightens a bit here. Then I modulate throttle to keep the car mid track through the corner and try to maintain 117mph or more, apex where that side road interrupts the inside curbing. Exiting 100R you can go to the outside curbing if needed but try to stay tight inside to the right to set up for the left of turn 6 the Hairpin. For a brake marker I use the small orange sign that's before the 50M sign, then arc smoothly down to 73mph to apex on the inside curbing, then immediate full throttle to exit to the outside curbing, hopefully staying on track and speeding onto the back straight. Finally I like to brake a little bit early on the back straight approaching turn 10, just past the overhead sign's shadow. It's better to smoothly enter the chicane than to overshoot it and blow T3.
Well that's my non-Alien way of doing sector 2. I hope it makes sense and is helpful. 👍
Drive fast and may The Farce be with you.
