Are you using the following workflow?

orgmode file --> export to pdf (aka weave)

orgmode file --> org babel tangle

Would you please help me understand your workflow for > jumping to the chunk which the code came from in the tangled source code on the pretty printed PDF

Do the codeblocks in your pdfs contain hyperlinks back to the org file where they came from?

No I'm using noweb. There is an option in noweb to add comments in the tangled code with the line and file from which they originate. Then there's an Emacs mode that let's you jump to that code. I wrote a little function that let you instead jump to the line in the same like in pdf using SyncTeX.
