I think everyone is getting a bit ridiculous. If the race is that close that small things like a nanosecond quicker response in flicking the paddle shifter or someones nanosecond reaction time etc than for all intents and purposes the tunes would be considered pretty much the same (given stock vs stock pulls are equal)
The real point of this is if the two stock cars are equal, to look for one of the tunes to be significantly faster. If this is not the case than it will be clear from the video.
Nobody is looking for miliseconds of difference here. Highway pulls with DCT tranny is about the easiest equalizer for any 2 drivers providing they can mash a gas pedal. Its an automatic and you slam the pedal. That is it.
