The exhaust system...

Is it through-flow?

Or

Are there any baffles along the pipe work?

you havent changed your fuel pump to match the cams and intake, the fuel regulator is doing its best to back up pressure along the fuel rail but i think you still need more delivery from the tank.

There is another toyota family fuel pump you can swap straight in with more CFM but i cant remember which it is, sorry.
