Adjust alignment of text inside TikZ

Question

A block diagram is generated with tikz pfg via Dia. However, the text inside the blocks is misaligned vertically. This answer says that it is impossible to do from Dia. So, how can following diagram be aligned with the text inside the boxes manually by editing in generated Tikz file. I use, LuaTex with TexLive. MWE

This is really a duplicate of that question and there are not going to be any better answers than those given there. Any programme which exports PGF/TikZ code tends to export code which it is very difficult for humans to edit. If the results are fine, well and good. If not, you are better off writing the code from scratch. — cfr, Apr 06 '16 at 23:30
Basically, what was said in this comment and in the answer to the question you linked. It would be easier to recode the diagram in TikZ. (Even in PGF.) If you want to use this, you must find each node in the code and either redefine the node or manually change the absolute dimensions involved. The nodes are created independently of everything else. Personally, I would either live with the result or abandon the code. — cfr, Apr 06 '16 at 23:37
I'm actually not sure what alignment you are looking for. Because all your nodes have virtually identical content, I don't even really see what is doing what. You have 2 lines in many of the nodes, but the code only seems to include 1 line per node. The alignment in the other question concerns alignment with things outside the node. I don't know if that's what you see as the problem here or not. — cfr, Apr 06 '16 at 23:40
Actually, the same applies to alignment in the node because the 'borders' of the nodes are actually drawn separately, I think. So it is a real mess and completely inflexible. — cfr, Apr 06 '16 at 23:45

The generated code is unmaintainable.

But your image is very simple to do with TikZ.
