    Hello forum members,

    Running the Bosch MED17.7.3 which required ECU removal and BSM communication due to the discovery it had been previously (Badly) Tuned.

    We had the vehicle for a few days as we had a full decat to rear silencer system fabricated specifically for the vehicle.

    After having the vehicle on the dyno and suspecting after initial road testing I could indeed come to the conclusion the vehicle was not stock. It behaved in a fashion less than ideal and throttle pedal felt terrible.

    As you can see the torque was up but power way down the management was fighting the calibration to look after itself.

    After removal of the ECU to see what had been done it was in-fact the same file I had previously seen on a number of E63s and CLS63s.

    Fully corrected the software and saw a huge improvement in every possible way.

    XXXX tune 518bhp and 921nm
    GAD Stage 2 (Corrected) 675bhp and 1185nm

    Below are plots, shots and videos.

    For any enquires please feel free to pop me an email to info@gadtuning.co.uk or call direct on 05603 67 21 09

    With a little foot control its very manageable!!! The tune that we previously on it had terrible throttle pedal manipulation and fuelling was a mess so customer is seeing an improvement of 3mpg which is also not to be sniffed at!

    Many thanks
