Now i am thinking again about the Mastertune , ( i did allready a thousand times ) , but we have different exhaust here in germany and i am not sure that Steve from Fullsac will be able to send me a perfect map within the mastertune .
Hmmmmmmmm

You can use the v-tune to make your own VE tables and get your own "perfect" map with whatever you run. It's closer and quicker with a good dyno operator.
With the help files, and some patience I'm sure you can figure out the program.
Again, to get really technical info, contact Steve Cole, I'm sure he can answer
ANY question about the product.
My '10 has no "map" with the combo I am running now, and tomorrow we will do a "custom map" to suit me. My '09 used a custom map that I ended up tweaking just a bit to suit my riding style and towing a 400LB trailer. This program will adapt to anything you can imagine, including big cams, big motors, large TB, trailers, you name it.
As usual, JMHO!
Hope this helps a bit.
