              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.

                          173 is the latest motronic. Adaptive. Most chips are made for the 173 too

                                      It should have a better power curve too wouldnt it? Maybe a little more power?

                                          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.

                                              So i bought one today from a friend for 20 bucks, without a chip. And i ordered an ebay chip, we'll see what happens.

                                                  One last question.

                                                  Will a 525 ecu be a direct plug in for my car as well?
