Got mine few days ago, did multiple before and after on the spot on a mustang dyno in these conditions:
Elevation: 16 ft
And very very humid in Dubai
Low end AFR was 10.8 (at low end) then goes to 11.1 or something close to that which is similar to stock PCM AFR (I can't really remember since it only shows on the print which I don't know where it is) but is richer than stock at low end, so it's safe since the tune is for CAI, Exhaust and a tsat, and I've only got a bwoody CAI.
Stock PCM has a rich AFR. It also ran cooler, no knock what so ever detected through the knock sensors.
Drivability? Well, I don't have to say any less or more than what KINGMONKEY and the others have said about it, it runs nice, it will run even better when I get my exhuast and maybe headers when they are available.
Did a 0-60 in 5.1 the same night, and after the 180 stat did a 4.8 today morning.
Will do a 1/4 tomorrow. Not quite happy with the 180 stat since it's struggling with our weather that the coolant temp is not even 185*, always higher, so I might go with a 170 instead but I'll have to ask if it will run alright with the tune.
Hope this clears many questions and doubts
All I can say is that I'm a happy man
