The JD needles do lean off a lot towards WOT. Throw a bigger main jet at it.
Their red needle is a H diameter from memory. N3EH#3 178 with the same pilot will make for some aggressive power.
NECW is a good choice for nice linear delivery. One step leaner on the diameter for clean delivery off idle.. and just builds. Similar in profile to the N1EF once past the first taper.
