Marco is right. Osh knows what he is doing I have read european car for a long time, Osh and RMS are the main tuners to supercharge an M3. They have been tuners for many years of other series like the 5 er and more. The main quote in there ads is "God is in the details."
Its my understanding that Osh is a person who has a very long history with BMWs, the other guy is just a poser.
By the way I have seen at Bav Auto Show, Marco's Purple M3 supercar for many years, this car is just awesome! Marco knows OSH due to the fact he has fine tunned the setup on his car and some other BMWs.
My only wish is that RMS made a supercharger kit for the e30 2.8 m20 325i stroker than I have made for my 79 323i.
