christian you never seen most bleed valves then, they have a + and a - and in the middle is the word "boost"
and technicallys just a turn would get you more power, when i first got shown how my bleed valve worked on my R5 turbo it DID make it quick, was fooking rapid when i turned it out totally and there was 5 of us in the car
5 seconds later the road was TOTALLY black
