Look, all of us are recycling the same points and making similar statements about the natural/normal hurdles of tuning a new single turbo setup. Point is, it can definitely be done and the S55 isn't something revolutionary to the point it can't lol
Let's focus on getting the "able and willing" owners or vendors on here to take the initiative to get something done on this sooner rather than later I'm saying. We want this option NOW while the car and bodystyle is relevant. Not old and outdated by the time 50 single turbo kits come out for it (a la E46 M3's)...
