It's been a long time since my bikes (2001 WR426's) were re-jetted, at the time JD offered lots of jetting insight but hadn't yet started selling his own stuff.
If I remember correctly it was EJQ and a 168, the difference was good.
I'm in SE Texas at Sea Level.
I'm certain his stuff is probably better, they were doing lots of testing back then on the best setup, and his products were the result of these tests.

See ya,
