I'm just curious to see if anyone has done a dyno with VDC off and on (same car/same day) to see if there is a difference. I know all the other VDC effects on brakes/throttle, etc. that could give impressions of hp/tq differences, but I'm just curious if VDC also "detunes" the engine a bit as well. On dry road runs with VDC off and on, I sure do get the impression (probably my imagination) that there's a bit more hp/tq with VDC off (driving with technique and in conditions where VDC shouldn't kick in if it's on).

Someone may have dynoed this already, but I haven''t seen any numbers on the forum. Thanks if someone has some ###...
