Hey guys, my name is Joseph. I have a 2008 BMW 550i with the standard tranny. Right now I haven't found much mods which I'm aware there aren't many out there. I've only found ecu chips from Dinan and a SC kit from a company in Holland called clubsport I believe still trying to see if I'm able to get it. Even then I have no idea where I can go or send it to have it tuned. I live in South Texas so I'm open to anything really. Mostly this post is to just ask for any upgrades performance and cosmetic that y'all know about. And I'm not looking for replies to let me know that it'd be easier to upgrade 535s because I already know that haha
