I buy the overall concept as a lot of people swear by the IPD/RSS/Mike's Turbo plenum that's the same type of design, just higher quality. A couple points of note though:
You've got a GTech windshield mounted device serving as hard data with such a slight difference between the curves.... Why on earth wasn't a real dyno used???
Port and polish.... come on! What exactly are you porting? The part in question is PLASTIC. How on earth are you going to really port that without making the plastic walls thinner and more brittle? Are you maybe knife edging the outlet side?
I've had the T after the throttle out on my '00 Boxster S. I must be really lucky as mine was already smooth inside from the factory.... perfectly smooth inside, no resin flash, no seams, no need for a polish. That's specifically why I had it apart, to look for a port and polish opportunity there and I saw little, if anything, you could gain without likewise porting the throttle body and also potentially compromising the integrity of the part. Because of the way the stock hoses and throttle connect I also saw no gain from knife edging the part. So I'm certainly curious as to what you've done!
Other than these points (and I am very skeptical by nature) I think the product has some real potential.
