I don't know....I just don't see a two mph increase in those intakes....especially with the Stage 1 cam.  I think he hay have had a better tune.  The Holley is the only Intake that I have ever seen a 2 mph increase on.  The Track Heat only flows 8 cfm more than the Street and the Holley flows 16.   
 
Also, the Street Heat made 13 more rwhp with my car on the dyno than my old Cobra.  Before the Blower and Stroker.  I guess you could say it is all in the tune, but my timing and fp was the same with both setups.  I also had a Stage 2 TFS cam.  The Cobra has less CFM 220 versus 245, and the EGR on the Cobra is a bottleneck.  I am not saying that the Cobra isn't a good Intake, it is just that I had phenominal gains with it.
