I would download the latest then, so the 110119.
If you start with 21 boost and 8 turbo, it's the same performance as the 518 (except that you have a lot more punch and a cool motor) then start adding more timing until your the fastest on the track, and still have a cooler motor and more runtime then you where used to with the 518....
