My custom tune from Jannetty came with it disabled.
T&T is doing my tune. I chose to have them do it thru e-mail and hone it in that way. More cost effective and I don't want to Dyno Tune it till I 'blow' it.

Maybe it is disabled. I do get a drone that's thereat certain speeds and is constant, but it just doesn't bug me too much.

With AFM all 8 are always available. Just not always firing.

I'll tell you this. Even with AFM active, it doesn't take a blink of an eye for those other 4 to fire up.

See, I'm the same. IF mine is still on and that's the drone I'm hearing, I'd like to turn it off. But I'm guessing mine is either off, or not noticeable.
