Have had RC for 5+ years. I did just upgrade to the RaceChip RS from the ultimate (mainly because I had some issues with the US 35d that are pointing back to the EGR being faulty (BMW pointed to RC) - hint/hint, get that replaced under warranty if you are nearing 7 years and 70,000 miles). I upgraded for under $400 and now can change settings with an external dial.
My need was when we were doing about 50MPH and the passing HP was lacking. RC makes a difference. It's also better of the line etc... Simple to install, talk to RG if you get a chance. Good video here too, they do provide feedback and testing to back their claims:
