No man, I talked a lot to Terry lately, there is a difference between the n63 tune and s63tu tune. They are similar, but not identical. For m5/m6 engines there is a difference in PSI and something else. So if you want to buy one for your car, make sure to ask Terry to program it for S63tu, as it requires a little more boost.

PS Yes it is a piggy back, my local BMW installed it for me (apparently it was super easy), and there is a huge noticeable difference, especially with all these performance parts
