Put it this way. Again, the TBs are CNC ported by a machine. Would you like a machine to port your TB nice and clean and consistent just like the last one that was ported before it or would you like a hand porter who maybe having a bad day or has 5 of them to do that day and wants to rush it through them all? Machines don't have a bad day or are worrying about BEER:30 with 6 more TBs to port. They only break down.

Most consistent info I got was better throttle response (maybe a + 1-2hp)...
