Calibrations for S-Manager - Use all calibrations at your own risk (dyno tuning recommended)

I am running this map in a freind's USDM B18C5 JRSC equipped car with RC 440 high impedance (12 ohm) injectors. The fuel trim in the calibration shows 510cc injectors. The car is ok at part throttle but extremely rich in boost and wide open throttle. Is it safe to assume that the fuel trim needs to be adjusted? Was this done to ensure the base calilbrations were "safe"?
i have the same setup and i changed the fuel trim to 440 injectors and im running perfect a/f. 11.78 to 12.02 in boost WOT. Only problem it runs lean at like 15 vacuum(light throttle) in 5th gear cruising. i need to tune this part of the map. my setup is 9lbs jrsc b18c5 84mm bore. 9:4:1 compression ratio. try changing the injector to 440 and see what happens. every engine is going to be a little different.
