Changes to my performance

Thanks to everyone who provided advice on changes to my M2.
In particular I'd like to thank the person who suggested I go back to school to find out what I needed. I did. I have fitted an O-spec 31/2 mid pipe, a Dahler valve controller and have had my ECU retuned (but i did have to do without the car for 2 weeks)
More recently I have had a carbon spoiler fitted to the boot.
Thanks everyone for your advice.
