Ok, picked it up today. I haven't heard any pinging yet. Tune feels pretty nice. Pretty much what everybody said already. Pulls harder down low, doesn't have that laggy build up time, just a straight take off.
Feels like it shifts a little better. Maybe its just me not having to avoid skip shift. Definitely worth the install so far. M/T 3.73
