A) You do not want to run stoich on a turbo car
B) How are you determining you're running rich? Let me take a wild guess here, an autometer bullshit air/fuel ratio gauge, right?
C) A FMU is only adjustable with different disks to adjust the step up ratio. IE: 4:1, 10:1, etc. A 10:1 FMU raises the fuel pressure by 10 psi for every 1 psi increase in pressure in the intake. That's how you get your fuel.
You shoulda done more research before you jumped in and bought a turbo kit. I'll bet 3 months later we hear a "why did my motor blow?" post when you try and boost 14 psi cause your friend told you to

Chip speaks the truth 
By the way, a walbro in-tank is usually fine if you're using some kind of real fuel managment (hondata, uberdata, etc..) with bigger injectors, but it can't keep up with the kind of fuel pressure an fmu needs. Might want to consider an in-line fuel pump like an msd so your engine doesn't pop.

It is this kind of statement that makes HT look like a bunch of stuck up ******* fucktards. If you don't have anything possitive or helpful to say, chill out and head over to GDD.
On a serious note you probably should ditch the FMU and get some kind of fuel management. There is TONS of information on here. I can get your ecu chipped pretty cheap by a close friend of mine. From there you will need to get to the dyno or have someone street tune it with a wideband. Tuning is a little expensive, but motors are hella expensive. Search is your friend but if you have searched and can't find it, don't be afraid to ask because some retard has a chip on his shoulder. Good luck!!
