    • ASR Engineering upgraded turbo 135i on the dyno - Over 500 wheel

      These quick videos were taken during the tuning/testing phases of ASR's 135/335 upgraded turbo kit. Never before seen until today.

      A big thanks to ASR for allowing Bimmerboost to be present at the dyno.

      Enjoy.
