I doubt it is dead. Sometimes you just run out of things to talk about until you acutually start doing it. I like the Rotrex units becuase the are more compact than other superchargers and hope he gets it running.

I would suggest you get your own Mercedes Star Diagnostic system. The Chinese clones work well and will cost under $1,000. I suggest buying one without the lap top and sourceing a T-30 locally or looking at a clone that works on any lap top. Let me know if you need info in this area. Also the guys at LET are very familiar with tuning boosted MB's and have experience with Star DAS and Developer mode.
