Well just on locking maps. When it is a very popular setup, say Ls1 with etc turbo. 2jz with etc. And this tuner(who it is his job and makes a living off) has spent 20-30 hours on each of his basemaps but only charges the customer maybe 3 hours worth(and his basemap premium that he has used 50 times by now) for fine tuning. If another tuner then sees this map and starts giving to his other customers, well it is like burning a CD
