A lot of BMW owners do it with the other cars too 335i for example, when they make a M3 for that purpose. I had a 4.8 and wanted to go faster, I didn't add a supercharger instead I traded up. I'm just asking for your mind set. sorry if I offended you

Yeah, it's you. Ask the tens of thousands of 135/335/535 owners who are tuned. My tuned 335i outran E93 M3s in the quarter. I would have lost around the track but I don't go to curvy tracks.
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.
