If you still have the PCII put it back on a dyno again, if the power is back then you have an issue with the PC3.
Dyno figures vary a lot, even on the same dyno, what time of year was it dyno'd last time? It's hot now so you will see a drop in power, when it gets cold again you will see an increase. There are so many factors that influence dyno numbers they can't be relied on. The only time I take any notice of dyno numbers, is before and after mapping, then you will see accurately the increase in power. Other than already mentioned, for me dyno numbers are a waste of time, and the only purpose they serve is for bragging. That's why I never quote or post dyno numbers.
I always do a before and after run, to see the difference, otherwise you are just guessing.
What was your torque figure last time compared to this time?
Might help if you post the graphs up, to compare air temp, pressure, AFR's and torque.
PS. Was it dyno'd in the same gear both times?
