no needle valve yet. will be doing that Monday..
from what I read the needle valve improves the delivery and can select the range of the boost but not the maximum... When I installed the dawes valve I expected to lose the spikes of boost that go to 20 but not also reduce the peak to 10.

Worry about it once you have the needle valve in. Whilst the needle valve controls spool up and mid range boost it still affects max boost to a point.
