SfanFZR used gofast + tuning, that's why he is able to take corners in such high speeds. 387kph is the top speed of CLK-GTR with tuned transmission.
In the section with 90 degrees turns (with theatre on your right), first take the right hand turn under the tree, then the left hand turn around lamp (over grass). -> You must explain it a bit more.
Watch 1:00 section of SfanFZR's record, that's the section (he does it wrong though).
You are faster in basically every section, because the car behaviour is just way different than on PC. We already said that.
