Highly satisfied with the tune from Dudmd. It really has transformed my f15. The customer service is top notch whether it's via text or email. Very friendly, willing to answer questions and help prior and after purchase.


I had a stage 1 flash done to my 335d on December 2020 via remote. Process was smooth and I love the power and smoothness of the engine.


I can not say enough about the great service that DUDMD provides - from answering individual emails, to giving you the best bang for your buck.
