cnc ported tbs

I've been very curious to see what people think of this new cnc porting of throttle bodies. I know its been out for a while now and was wonder what kind of results people are actually having and if they like the throttle body??

besides the cnc program is just a copy over a good hand ported design then duplicated each time a new tb is loaded into the machine. it takes the human error factor out of it.

Just because its memorialized in a CNC form doesnt mean it was "good" to start with

you might be right about the claim of it being 7hp over a hand ported job but it is never said who the hand ported job was done by, for all we know it was bigfoot with a file going to town on the tb in the woods...

Yea that what i read to and didnt believe it so i figured i would let time roll by and see what actually happened. Maybe they are including a tune with it to gain 7-9 over hand idk. Thanks for the imputs guy!
