There def is faster "FI" M3's out there. 320WHP NA, stock internals? Sounds like a happy dyno for sure. When all I had was 3.91 gears, and BHS pullies, I ran even with a car that had just about every bolt on available with 4.10 gears, bolt on mods do very little, traps and comparo's indicate this.
Can you take procede 335I's or is it close? N/A my car was close to full weight, made roughly 278ish WHP, and every stock 335I with procede I ran was a decent run.
You crazy, lol, FI doesn't ruin the S54 in the least, the linear powerband is the same, the smoothness is still there just more power on tap, very streetable, etc. and the AA kits have more than proven the reliability of boost and the S54, celebrate. :rocks:
