Seen this was a little old but didnt see where anyone ever answered you.
It wont matter to the pump what injector size your run, my 45's are maxing out the stock pump at around 2100us. I dont know the exact numbers but the difference is... (for example) the 60's may be maxing out the stock pump at say 18-1900us making the same power. Your are just putting the same amount of fuel in the cylinder in a shorter amount of time. All in the tuning
