It was a huge improvement with the dinan stage 2!!! It way quicker than before and sounds a lot better now too!! It feels as quick as a 50i now but handles better. I highly recommend it for anybody. The m performance just adds to everything especially the sound!!! Yes it costs more the the jb4 tune but warranty is still very important to me. I have had Dinan tune on three bmws and not one issue. Other than they don't have a tune yet for the 2014 335i that I have ordered.....
