Well, these figures are conservative, as they often are from BMW. The following video shows the E90 335i N55 PPK (also factory quoted at 320hp 332 lb-ft) producing 336 bhp / 377 lb-ft torque on the dyno (performed by Dinan and at a 15% drivetrain loss).

Just as a comparison with what BMS posts for stage 1 dynos (I took the lowest numbers btw)

Stock car:
278whp/292wtq
328bhp/344btq (figuring approx 15% loss like the post above does which we don't know to even be accurate)

JB4 Stage 1:
307whp/340rtq
350bhp/400tq
So you think it will feel MUCH less powerful than my jb4 stage 1? Shit. I have to try it anyway.
