Go GIAC or Cobb.
I went Cobb so I could flash it myself. Love the Cobb no issues.
If you do a search here you will find Cobb has/had oscillation problems as well which makes me think it might be an inherent problem in BMW software somewhere down the line that is not really exposed till certain performance parameters are increased. But again, why it happens to some and not others is a great mystery.
