RPM Performer vs Systemax vs TFS-R

Ok,
I have been working alot of numbers lately, below are going to be some numbers on the Edelbrock RPM Performer, TFS-R, and the same cobra vs holley systemax comparision.
Again, this is on a stock 5.0L motor with stock cam, TFS heads, exhaust, pro-m80, and a Vortech S-trim through a T-5.
From what I gather, it honestly appears that the RPM Performer out weighs the other intakes, except for down low. In the Mid, and high the rpm performer really seems to be the best for this particular car. However, more boost, and a cam may change this.
I'd really like to see more articles or dyno comparisons of intakes.

TFS-R

It appears to me that the Performer RPM is a killer intake! I didn't think that it would be better than the Holley though... I have the chance right now to get the RPM for like really cheap! I may just do that now..
