Rebuilding engine sometimes makes wonders. Also if I remember correctly, that turn outside of tunnel was a bitch on ps2 mission where you had to get above 300 km/h on a finish line.
Thanks for translations /r/WanganMidnight and @Dridespoon for bringing it all together. Merry Christmas and Happy New Year
That's the bend that a loooot of SRP (Assetto Corsa) players crash on because it's a relatively severe corner if you're just coming out of the tunnel at 320kmh.
