Donno bro, their website seems a bit cheap lol. On the other hand, they seem to reflash nearly most of the cars. I don't feel confident with tuners who are specialized in Everything lol I like to go to a BMW specialized tuner or so

They aren't bad they did my Jeep SRT8 and got an additional 40 whp out it (for free - my truck was the prototype), not sure I would trust them with BMW though, unless we can get some positive feedback from users who bought it.
