What are the thoughts on the DINAN tune and if you get it, would get the DINAN tag on the trunk lid?

I have JB4. It will void your warranty if the dealer knows about it...but JB4 is really easy to install/un-install. I used JB3 for 3 years on my old e90 and I've been using JB4 for a while now. I don't think that warranty should be a huge concern...you can always read and delete codes and un-install it before going to the dealer.
