What do I see when I look at these charts....? A couple of things.
The first is the fact that the 'stock' torque fell off like a brick after about 6,200 RPMs, versus your cars nice extension past 7,000 RPMs. This looks dramatic and makes you wonder if they kept the stock Cayman pegged. But it does make sense. The exhaust and intake mods that you've done will provide the most benefit in the high RPM neighborhood, so I'd say that's an incredible improvement and consistent with your mods.
The next thing that I notice is a dramatic drop in the torque of your modified car from 4,700 RPM to about 5,600 RPM. What could be causing that? My guess, the elimination of the distribution flap on the 2 stage resonant intake system. It just so happens that the resonant flap is programmed to open at exactly 4,700 RPM. My guess is that since the first circuit of the 2 stage intake has been removed, the 2nd circuit is all messed up.
