That is the exact opposite of what you should be seeing. For now, walk the main jet down so there is no more splutter at WOT in 3rd. That will put you pretty close to where you want to be.
The trend is for second gear to rev out clean now matter the jet, but for 3rd and 4th bog rich.
I will also repeat my suggestion that you keep track of your speed (gps only, Stella speedo is just for decoration) as a cross-check. With your setup, you should be doing at least 60 mph on the gps if you're revving alll the way out in 3rd.
