I did read most of the 2.5tdi tuning thread..... alot of which was beyond my skill/knowledge set.

I have a full stainless system, is it worth removing the cats/particalulated filter?????

Yep, it will spool the turbo quicker and won't be much noisier than with cats... Cats are a big restriction on that engine.
