Maybe to give users the same "feeling" as with Tekin?
If Cobra didn't explain, we would have never asked, and maybe a Tekin is working exactly the same, 40 boost and 30 turbo, so you think you have 70 total dynamic timing, but actually it might also be less.....
Tekin is 55 boost and 20 turbo, HW is 30 boost and 16 turbo.
The question is, why is there the possibility for 38 boost and 30 turbo and how does this works and what are the advantages?
