Don't use an FCD... its tricking the computer by making it think its running lower boost. I recommend an Rtek. It, instead of not having fuel like an FCD, adds fuel above stock levels and retards timing a degree per PSI above 9psi. It also smooths out the staging points. Pretty inexpensive and a safer route for a simple TII w/ a turbo-back exhaust, and ported waste-gate.
