It truly is night and day. I had a dash mounted Edge Evolution on my previous truck ('07 F150) and it was the same. Really opened up the power band, allowed me to see real time performance and data, adjustable tire size, gear ratio, shift points and firmness, all sorts of stuff. Loved that thing. I think that's my only gripe with the inTune is that it's really just meant for flashing, not mounting, and that it's slow as molasses. The Edge took maybe 30 seconds to read, copy, write, and be done. The inTune takes considerably longer.
