So you are comparing a stock LS7 intake that you ported vs. a ported Fast 102, both with the same RPM heads, correct?
Cam and headers on this build also???

From observing the design of the FAST, porting looks to largely benefit the low-mid range areas, where port velocity & transitions are key. On the topend for max flow, I doubt porting actually does much to improve total airflow.
But in an all effort NA car, this needs to be part of the menu, so as not to leave any scrap of hp on the proverbiale table....

The Fast is very clean out of the box and if anything needs only a minor clean up to match the runners to the base.

Essentially this is a cammed LS7 with headers, CNC heads & a ported intake manifold.
The heads have our CNC porting, CHE guides, SS exhaust valves, and a spring kit. The heads are milled & I'm not going to divulge the CC's other than to say that they are milled to match the combination and ensure 91 octane fuel is acceptable.
The manifold is our ported version of the stock unit.
I'm not going to divulge cam specs, but it's not that wicked.

The dyno's now do a pretty good job with correction. With experience you can make very accurate analysis based on the shape of the torque curve.
