Lemmiwinks is pretty basic. It reminds me of an S-AFC or some kind of piggy back. The idea with that is, say you have a "stage 3" car, so you get a stage 3 off the shelf tune, you can use it to fine tune. Sounds like Thorne has the best equipment, I'd go that route. I just have no clue about eurodyne stuff, it's not really used by S4 people that I know of so naturally I'd go with things that I'm familiar with.
