No worries there is power to be had by running higher rail pressure. Just making sure I wasn't missing out lol

Thanks for the info

I know it's apples to orange, but my truck will hold over 25,000 with my setup on the 310 tune. I think it's the ported rails and a low mileage pump. It will usually hold 24,700-24,800, but it has held over 25,000.

Thats corrected. Those numbers are with a spartan 310 tune. Its a little smoky right off idle but cleans up fast.

Awesome. If I ever did upgrade the fuel system, I would do something similar. Modded pump and 60hp or 85hp over nozzles.

I wonder what that setup would do uncorrected at sea level? Similar to the corrected numbers up there I would guess...
