Hello, decided to join the forum as I would like to learn what fun can I do with my N/A m54b30 engine that i swapped into my 320d E46. Got the tuned Schmiedman Headers, and after reading ms4x.net I managed to make easy mods like hard cut, throttle response, and i removed my post cat probes. Now I would like to learn, if I can get some tune regarding the aftermarket exhaust, or maybe not =D
