Probably my imagination, but my mpg seemed to decrease after I swapped from 153 to 173. Sold the 153, so now I can't swap back to test it. Do like having the stomp test available tho.

I just did this...and started a thread just like this
its plug and playComment

what is the diiference between the 2? why would swapping them be a good thing?Comment

173 is the latest motronic. Adaptive. Most chips are made for the 173 tooComment
-
how much $$$$ is one of these things because i have a WAR chip but havent installed it because the 153 is not an option on the softare selectionComment

Assuming both are operating properly, there will be no difference in performance. The advantages of a 173 over a 153 DME are better idle control, the stomp test, and easier access to performance chips.The car makes it possible, but the driver makes it happen.
