What pump are you using? and are your injectors 96# at 3 bar? This makes a big difference......My injectors are 92#'s at 4 bar (58-59Psi) and i maxxed out at 8#'s with a vacumm referenced regulator i never got above my base 60psi so i know i ran outta fuel pump.... Im sure it has to do with being a 408ci motor and a pt88, but i was running 84% duty cycle at 8#'s of boost

I have a 255 in tank running thru the stock line, and then a fitting in the bottom of my tank, with another 255 that sits beside the tank. The second 255 has it's own line that ties into a 2nd fuel fitting I added to the stock rail. So both pumps and lines are seperate and run into the same rail. The 2nd pump has a check valve in line, and comes on at 10psi. The check valve keeps fuel from feeding back thru the pump when it's not running.
