My 1000 K7 was flashed. I posted this in the beginning. I had a shop with a dyno do it using a yosh box. I am not sure how much adjust-ability the parameters have, but mine had a hugely annoying stumble in the 3000 rpm range that drove me nuts. The tuner got rid of it and the bike ran much better....like it should have from the factory. The tuner said it picked up a few horsepower, I took his word for it.As far as I know there are no Vee's that have been flashed. No data or charts to compare.
BUT....it came at the expense of some fuel mileage. I dropped from around 40 mpg to 35 mpg. It was worth it to me.
