The N63 (50i) and S63 (M) engines are not that much different. The 50i with a stage 2 BMS tune is dynoing at 450+ whp Do the math. With a 15% drive train loss, that's 530 horsepower with no other mods. For under $700.
It is very easy to find big gains on a turbo motor using affordable ECU tunes. Your 4.8 was normally aspirated. You would have had to spend thousands to supercharge it.
So yeah, it's you.

Just curious Why did you go with 50i vs the x6m, is there a large difference in price? You obviously wanted a fast suv so why not just go all out and get the M? Test drive anything else? If you have just a 15% loss in the power train I wanna switch transmissions with you!!!
