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!!!
