I ran my M3-DCT against a stock 335i and by about 200km/h, I was ahead, did this a couple times. I had a couple of runs the other night(near Kyalami) with a 335i and he was gaining on me on both runs. when I tapped off at about 160km/h, he looked like he would have come past easily but couldnt because of traffic. I can only assume it had software.
The gains on the M3 with software only) up here are not fantastic, compared to the x35i, so it is difficult to really compare apples with apples.
I sold my 335i the M3, and initially I did mis the car but after driving the M3 for a couple of months, I realised that they M3 is an all rounder, whereas the 335i just wasn't and I sold my E46 4 pipe for the 335 a few years ago.
