ok well there are a couple of problems with your setup...

1) stock injectors...stock injectors cannot be used on a turbo kit...they dont provide nearly as much fuel as they should for a turbo kit
2) FMU = bad...fmu just jack up the fuel pressure to add more fuel for the added air produced by the turbo...this can cause the fuel injectors to go bad as well as the fuel pump

my suggestion is dont run the car till you get a lot bigger injectors and a standalone engine management to tune it...that will take care of your fuel cut

Even after you buy the hondata you will still need it tuned by a local shop. You could mess something up with the injectors being that small. I would go with at least a 550cfm injector, and a walbro 255 lph fuel pump.

if you have any local shops they should be able to get what you need. also you can also use DSM 450s for a better prices

I agree with everyone who has said that you need bigger injectors, a stand alone, and a tune. Proper tuning is key!
Also, I have a question: What engine management have you been using thus far?

i highly doubt it that there is an aftermarket standalone on it cuz you still have stock injectors...i bet its just a FMU 12:1 and thats all

The DSM injector setup would be great if you are still running the OBD0 with the resistor box. No need for inline resistors.
