I'm not worried about the Dinan, I'm more interested in what BMW has to say re the boost etc from other "competitors". I have 27000kms on it with over 17000kms on Stage II with nothing but praise for it...
I bought the Dinan because it was a total package of reprogramming rather than just a turbo boost AND it was warrantied.
