While doing the flash, Tom showed me the plots for an '08 with 48k miles, original plugs, and old software. The owner brought it in because it failed smog. It put down 308 WHP and the plot was rough like yours because it was misfiring (no codes though). With new plugs and software, it made 345 WHP.
I just received an update on this particular M3 this afternoon, it passed emissions with flying colors.
