You're crazy to even be trying to do a comparison like that.
Have you checked for boost leaks?
Whats your comp ratio with this new setup?
If anything you need to take a look at how your g/s compare for starters.
To say you should be running the same amount of timing to make the same power is simply not true. Two timing curves can be completely different and make a similar peak power. You can use it as a reference but dont think thats what you need to run necessarily.
