trouble with 30lb/hr injectors

I have a set of FOMOCO 30lb/hr injectors that were recommended to me for use on my c900 LH 2.4 EFI system. Unfortunately they bog the engine out at high rpm and cause the exhaust to smell like raw fuel at idle.
I've tried the 300 ohm "fix" and have even tried many different settings with a dash mounted potentiometer. Noticed somewhat of an improvement but not ideal. AMM is brand new. The stock injectors seemed to give better performance. Makes sense as the fuel delivery calibration was performed on stock injectors by Bosch, so introducing injectors with a 50% higher flow rate for the same duty cycle doesnt make sense. Why not just increase the pressure in the fuel rail for the same result?
What flow rate are the stock injectors? 19 or 21lb/hr? Has anyone gone with 24lb/hr injectors and noticed significant empirical improvement without any modifications to the AMM signal?
Thanks
