How relieved I am to have an educated discussion here. This board is quite different from E36. Frankly, I don't have a 7, but I have a V8 5. So, I check this forum frequently to find usable information. FYI, Racing Dynamics has a power package for M62 engine (4.4L V8) that includes ECU download, exhaust and cams. They call it the R44 power package. Let me know if you're interested.
