Seems normal to me sir. It's not all about absolute boost pressure. 24psi of air at 10degrees C will be a lot more combustible than 26psi of air at 40degrees C. No i haven't done the maths, but you get my drift.

I can't imagine there's any boost leaks as it's going really well
Yes but as in my above post, the turbo may not be producing enough flow to build up the boost you had before. It's not pressurising a static chamber of air, the engine is eating up that air at the same time.
Ok buddy what u said makes sense, I should probably up the pressure a bit then.
