Well yes and maybe no. If your running an FMU with stock compression probably yes. If you dumped the FMU--
no. Probably require 50lb'rs. If you lowered the compression the 50lb'rs might possibly be at their limit. Hope this helps

I agree with the above post. If you maintain the FMU, have a healthy fuel system, then the 30# units will probably suffice. I run a little more cubes and am running 36# injectors with the FMU. I am looking at switching to DFI, and would ditch the FMU and step up to 50# or 55# injectors.

Are you currently running on the 30# units, or have you not started it with the new 383/Vortech combo? With a Diacom, you would be able to tell very quickly whether the 30# units are adequate.

Best of Luck,

Aaron
