I think you'll get a better answer if you explain a bit of what you're actually asking. Your message doen't say anything about what you want to know, but I'm assuming you're asking about a tuning chip from dynamic diesels from the title??? Give us some more info or a link.
It depends on the year of your 2.5, earlier ones the chip is soldered to the board where later ones have a chip base if your lucky and can be changed easily....
