Low injector duty cycle on power FC

Low injector duty cycle on power FC
Just put in a new walbro pump , ( thanks Ihor) and now im seeing max duty cycles on the commander of 45-47%.
I ran a search and read for hours but everything is for going over like 95-100% duty cycles.
So im thinking that they are stuck shut. Or going bad ie: not spraying.
I know there is some kind of test to do with a 12v. line attached to them and listen for a clicking noise. But I really don't want to break ****. If I don't do this right.
Also when im at like 100 and gun it I feel like the engines just rev.s high and doesn't move anymore. Then I let off the gas real quick.
Should my duty cycle be higher?
Thanks for the input.

HC is too high

Why would changing out the fuel pump affect duty cycle? Duty cycle is primarily determined by rpm and boost. There are a few other things that can affect it such as water or air temperature, but I can't see how the fuel pump has anything to do with that. I guess you are just reading it off the commander. What rpm and boost are you at when you see 45%-47% duty cycle?

Duty cycle is based on the fuel maps and injector flow rates, it has nothing whatsoever to do with fuel pumps or physical condition of the fuel system.
Your other problem is a slipping clutch.
