The differences aren't huge.

Tyres and wheels also play a role in power output.
I wonder if the reduced exhaust restriction on the car with the Akra exhaust caused lower boost? Way back when I had a positive displacement blower on a car the boost dropped 2-3 psi when I went catless, but made more power thanks to reduced IAT's and better exhaust flow
