For 4x the bucks does the IPD deliver 4x the performance of Pedro's?
On this test of a Cayman S published in European Car, they measured:
Baseline
Peak wheel-horsepower: 260 @ 6200 rpm
Peak wheel torque: 223 lb-ft @ 4400 rpm
Maximum power gain: 13 whp @ 5900 rpm
Maximum torque gain: 13 lb-ft @ 5900 rpm

Can one feel this ~5% peak gain "seat of the pants"? Very likely. Is this going to produce dramatic real world performance improvements for a street car to justify the cost? Doubtful, but let's see some objective tests.
