The "tunes"were compiled by hand without any dyno or means of testing other than trying them on his own bike. Basically, he simply played around with enriching the mixture at varying areas of the rev range. Nevertheless, a lot of people loaded them and were satisfied with the increased performance... which of course you will get from any enrichment over the factory's (mandated) lean settings.
Your call, so long as you don't expect any assistance...as he is long gone from here. Stacked his bike and went elsewhere.
