Yesterday I went over to Sparks' house and we put a 60MM messaged Throttle Body on my 'Tour. The butt dyno tells me I feel the difference in the high end (or MY bottom end). It didn't take us long, 30 min, and it is well worth it.
I left him my stock TB and he plans to message it so someone else can use it.
Sparks put a 65MM and we went for a ride in his 'Tour and it is a beast!! I know that it has helped his 'Tour...no dyno needed!
