My pb iat Buttonwillow is 1:54:7 in a e90 m3 no aero, stock brakes, kw, and safety stuff.

That's a good time! I don't doubt you can drive, I think it's more so about just understanding the quirks of a car... every car has it.

That said, I've just updated my entire car again to the latest ISTEP as of September. Any bit of power lag that I've felt before between shifts is really smoothed out, on aggressive shifts there's 0 lag. If you're ever in OC you can try it out..

I think on the street it's different though. Maybe it was over the course of several laps or something?

What's istep?

BMW's fancy term for software integration level ( total software version of car )

Previously I experienced the lag quite often.. now it's only in rare conditions. It's definitely made power delivery way smoother on the M2. My car originally was pretty new as well ( 02/2017 build )
