Sorry, no hard data or track times but just figured i'd add some more qualitative info. Went and picked the truck up due to having forgot some chit for softball game tonight and starting to really notice how much more enjoyable the truck is to drive. Acceleration smoke has been cut dramatically now being able to roll into the throttle without generating anything more than a slight black haze where as before it was a pretty thick black haze. Truck is simply tons more fun to drive with much more bottom end! Also, EGTs are staying a good bit lower everywhere and is really noticeable when letting truck cool off before shut down.
I will try to get some 4x4 launch video up comparing how the truck was before the spool flange and now.
