Yes, keen to hear how the car has changed. Positives and negatives. I have a 2013 M5 and know DMS well, they have tuned the last 4 of my cars. Rob is top class.
My reluctance to have the M5 tuned is really the car is already extremely strong and at times it struggles to get the power onto the road. Do you see gains on mid range, etc? |

You could either go with Hartge or AC Schnitzer (ACS also offer warranties and their tunes are normally TÜV approved). These are so called piggy back tunes (additional ECU) that are easily installed and removed. These can be sent and installed locally (even by yourself). Or you could use companies like Manhart, G-Power or PP Performance. They will need your car and reflash the DME. This also gives more power than Hartge and ACS. As of now, it's only ACS that has a independently verified removal of the speed limiter. |

I find forum bias very interesting. I don't know how much power this guy is making, but when faced with the proposition of over 700hp from a tune or inaccurate dyno numbers, the person who suggested the dyno's may be inaccurate gets flogged. Kinda funny. |

Dyno'ing in the wrong gear can skew numbers, but the difference is generally small on inertia dyno's and nonexistent on load based dynos. |

Some (Coldlist) has alluded to a dyno procedure made by BMW (that is as thick as a book) for the M5. To many that hasn't added up with voiding warranties etc, if they actually have made a dyno procedure... The thing is, during EU type approval the car has to go through a emissions drive cycle simulating Urban and Extra Urban driving. This is done by a technical service (usually TÜV), and can't legally be done by BMW themselves. These tests are done on a very advanced rolling road dyno, that is able to recreate aerodynamic losses and inertia etc. To be able to dyno a modern car correctly, the manufacturer obviously needs to provide a manual/procedure by which the technical service can test the car properly. Hence the manual on "how to dyno a M5" |

I realize the DME can't "fool the dyno" that was actually my point. |
