4TH, poll makes no sense.
I wouldn't work with Hennesy, very expensive and haven't heard much good from him.
Lund makes great mustang tunes, and seems to have a strong tune for the Explorers but have never worked with him.
LMS tunes in both of my EB vehicles. With Rick LMS was untouchable. Lately it is still good, just not at the same level, IMHO.
Unleashed, Torrie seems to be spot on. He emailed me everytime I emailed him within minutes regarding tuning my Explorer. Unfortunately he has nothing available as I was going to use him as I like SCT products much better than the hypertech programmer. It can do very little except load a program and from what I can tell is not even backlit, so difficult to impossible to use at night. It does load much faster than the SCT though.
