With an ECU Tune, NW CAI (dual or single), and a Code 3 or 178+mm SC pulley, you have a very real chance of winning... A stock E92 M3 runs somewhere around a ~~ 12.4... which is not at all a weird number for SRT6 owners that do the above mods.
In fact many members have SRT6's running in the high 11's, and many many more in the low 12's... I wouldn't be suprised if over 1/4 of the SRT6 scene has some type of performance addons.
