If anyone reads European Car, they had a dyno of the PPK and it showed a drop in peak torque and a slight increase in HP. They questioned the results as well.
This is the same car that was pitted against the modified ATS in one of the other magazines (motor trend?). It makes sense now as that test showed the PPK car running stock like numbers in the 1/4 mile.
No idea how to get the image at a higher resolution
