This man knows coding and helped me install the latest DME on my 12' E88 (post locked). While I couldn't get the PPK the DME fixed my hesitation and surging issues. I swear the car now feels like it's on sports mode during normal driving and with the button pressed even angrier! From the date it looked like it was the DME from the factory!
Very professional and communicative throughout the process. Good stuff!
