yeah, stock. bmw's published dynos from their marketing info, to be exact. It would have to make a good deal more torque (400-450 lb-ft or so) to make up for those huge deficits in 1st/2nd gear. Not super familiar with all of the N54 tuning, but a piggy back is not going to get you there. At that point you're into, what, somewhere between 15-20 psi, race gas, thousands in turbo upgrades? At which point you're probably only a couple thousand away from an M3, with which you wouldn't be sending your engine to an early grave whenever you get on the gas.
Not dogging on those who like to tune their turbos, that's fun stuff, and my intention wasn't at all to put down the other car, or say that you cant make a car perform better with some mods. The point was that you really need to look at gearing to make any sense at all of torque numbers. When you do that, you can see that the BMW engineers gave the M3 far more torque and a wider torque band than the 335.
Saying a car as 200 lb-ft of torque vs 250 lb-ft means nothing at all without seeing how that torque is being multiplied and put to the wheels. I think people's attention spans are generally far too short to realize this, which is why we get the "M3 only 295 lb-ft, lolwut?" comments. So, just kind of an exercise to illustrate this.
