I am no expert, but from what I have read around here the car responds much better to meth when the car in question is running a specific meth tune. Dinan does not give you the option to switch maps at all so I don't think you will notice the typical gains of say jb4 with a meth map + meth.
That said it is essentially upping the octane so I would assume it would give you some sort of gain. I would recommend against it though. Ask over in the N54/5 engine forum, they will be better able to answer your question.
