I mean no harm and chris is tight but the M5 needs a driver mod in the video. They are pretty hard cars to shift right and you can see it lurching in the video pretty bad. Does that 335i really have no mods? I know they run mid-low 13's stock so the driver is excellent. M5 should of pulled the 335 as they can run high 12's/low 13's at 110 stock. Maybe chris needs to check his 02 sensors etc as thats a must to get E39's running right. M5's are known to loose 20-40hp if they arn't replaced when needed and they are tempermental bitches.
