If the exhaust is not going to have a catalytic converter, you should port the wastegate before introducing a free-flowing exhaust. You will start to see boost creep over the stock 7.5PSI. All is has to do is hit 8.6 PSI and you will reach the fuel cut level.

720cc secondaries (you will need 6-10 ohm resistors to bring the resistance up), a bigger fuel pump & fuel control.
