55 massey injection pump

I have a 55 massey harris diesel that I pulled last year and it was a little short on power. The rpms have to be stock, 1500 I think. Is there any way to get more fuel in it by adjusting the pump? Or to get it to start fueling sooner? My 55 has the earlier american bosch APE inline pump on it.

I think I was told bigger plungers could be put in the pump, but I was wondering if there is any adjustment without changing the rpms?

Thanks,
Kyle
 
I haven't looked at that pump for a while, and my memory is foggy. I think the adjustment is under the cover on top of the pump. That pump will put out a LOT of fuel and make a big difference in your tractors power.
 
pump looks like this one, well if the pic will load.

Thanks,
Kyle
