Default Maf maxed out?!?

I have a 5.3 with a ls6 cam and a turbo on 8psi. The maf is pretty much maxed at 8 psi but I want 10 psi! I want to stay maf so what are my options?

go to 9psi, and then 10 psi if the afr and timing still look good.
Can pull a degree or two of timing from the far right side of your timing table before hand and add it back slowly.

Maxed out in hz. I've had it to 10 psi but it wouldn't stay steady! I've been told the bigger pipe would help but I was wondering would a bigger maf like linginfelter help too?
