Default To add to the Fuel Cut topic w/o stealing thread

i have the HKS FCD...my engine is bored .50 over,NGK plugs and wires, i only have a stock turbo and a MLS HG,ARP Studs, hallman MBC,Turbo XS BOV, and a make-shift intake (cone filter) im only going to run 10 psi until i do fuel pump and such. i was going to put the FCD on but do i even need it for this stage of upgrades. as of now stock fuel system but my next move is Walbro and 550's... also would really like to get my hands on a lexus AFM...
does anyone know what a car with this upgrade level should run?

Uhhh what do you mean you can't get the turbo off? So you are saying you left the exhaust manifold and turbo still bolted to the head when you did the head gasket? Then how did the machine shop plane the head with it still attached?

You should not hit fuel cut at 10psi.
