I am also running an Epic tune and am extremely happy. I think I was the first to go to Randy after the issue with the Evolve map and their airbox.

I can confirm there are no issues with heel-and-toe or the cold-start engine hunting, all a result of the car still running in "limp" mode (try disconnecting your MAF on a "standard" tune and all these issues will arise).

The map is strong, and clean through the power band. No discernible flat spots etc. Idle sits a little high (950rpm), but I'm sure could be tweaked but I just haven't gone back to Randy to address this as it doesn't bother me so much since my Z is a weekend/track car (actually in some ways I prefer it, as with my VT Race engine/transmission mounts, the higher idle rpm means I don't get any vibration at all), but I guess if I was driving this in the city i would suffer some mpg loss.
