2.5TD 19J Turbo Boost Pressure Numbers?

I installed a boost gauge and was wondering what I should see on the gauge while driving. I understand the principles of how a turbo works but not sure why my boost seems to vary based on what gear I am in. Is this normal?

In first gear the boost increases and then when the accelerator pedal is about 2/3's of the way down, the boost drops off. In Second gear the boost continues all the way up to about 10 and stays there as long as I keep the accelerator down.

Should the boost increase in all gears and peak out at around 10?

Probably less load on the engine in first gear?
