Wow, 170 mph. That power bump makes a big difference. On a stock engined car there won't be the same issues because you won't see those speeds. I can understand wanting more than Normal EDC. What I still think of as "sort of smooth with undulations" you see as "bumps". The best I've seen with stock power is a tick over 140 mph into Schwedenkreuz. I should probably be able to hit close to 150 but you've got to be doing 170 or probably better into there as well. Perhaps that's what you mean by the "first main straight"? I'd love to ride a lap with you.
