Raptor seems fine, but my and my wife's ecoboost suck's while in drive and stopped at a stop sign. Runs smooth for say 10 seconds and then it'll bounce around a bit and run rough and then smooth right out and then it'll do it again in another 10-15 seconds or so. It's annoying enough I'll shift to Neutral until time to move since she doesn't want her's tuned.
I tuned mine and upped the RPM while in gear and it fixed the issue on my Eco.
Different tuners have different 'available' options but mine lets me set idle rpm while in park and idle rpm while in gear, each its own setting. There's a bunch more available.
One more thing, altough I haven't read this on the 6.2, my Eco was really bad at first, but I found the plug gaps all over the place. Once I gapped them all the same it was much better, but still had the same issue above. Anyway might be worth checking plug gap, but a tuner should help.
