Their asking $650 for this thing and saying 19% increase in flow? 78mm throttle plate??? I've heard porting out your throttle body will be good for a few extra ponies. Is this basically the same idea? Just paying for the Callaway name?

Love the Callaway cars but would have to agree you are paying for the Callaway name.

If Callaway engineered it I would bet its a good buy. Callaway, Lingenfelter, LG Motorsports, some of these names in the industry I trust because they've been in the industry for so long and always seem to come out with pretty good stuff. Thats my 2 cents.
