Looking to sell my Dinantronics Elite kit. Came off of my 2017 M240i xdrive, no issues with it at all. I needed something more customizable for my application.
The car feels much quicker with this and has Dinan's warranty to back it up but I believe you would have to have Dinan/BMW install it. I would also double check if this is still the case with getting this second hand.
If you don't care for that, this is super simple to install and I can walk you through it or just do it for you if you are local, should be about half an hour with a beer.
Advertised gains (found on FRSport):
Max HP Gain:47 @ 4500 RPM
Max Torque Gain:60 @ 4000 RPM
Peak Torque:438 @ 4250 RPM

Price is OBO, feel free to ask any questions.
