It's wobbling because the turbo dynamics are too aggressive. It's overshooting target boost, over compensates, so it goes under target, then over compensates, goes above target, etc.
You're going to hit slightly higher boost in higher gears. As long as you're hitting target with close to zero turbo dynamics in 3-4 then wastegate duty needs to stay the same. Turbo dynamics are too aggressive.
