Tuning is the only issue, if there is one competent tuner who can custom tune the car we will see upgraded turbos very quickly. The hardware part is super simple it's just being able to make it all work. The good thing is there are several companies currently working on tunes for this car and since already came turbo'd you'll never have to figure out as much as an E60 M5. As soon as there is a proven tuner who can do custom tuning I will upgrade my turbos.
