"You really cant any higher then 10 psi safely without a new fuel setup (fuel computer at least). A power FC should let your un about 12 psi safely if tuned."
"I've been running 13 psi with a PowerFC with no problems. But it's more than just upping the boost. You'll need to mod the intake and exhaust as well."
