11th Dec 13 Review for BMW 120d 184 2012-) I fitted the tuning box to my BMW 120d 184 and awaited the grin on my face increasing, BUT I had put the boost plug in the wrong way and didn’t notice much difference. After talking to Andrew from DTUK I turned the boost plug around and fitted properly…..then I tried the car…..😄😁😄😁😄😁😄 What an improvement! Can only describe it as a rockets ship now. Another happy customer!! If you do buy a box and have any problems at all, contact Andrew, I’m glad he phoned me. Words can’t describe the difference, you really need to try it to believe it. It turns a great car into a better one. Jim from Scotland
