There are a couple tuning challenges with your combination of parts.
Timing Table - http://www.gearhead-efi.com/Fuel-Inj...-Throttle-ONLY!
Base Pulse Width (BPW) - The 18 lb fuel pressure regulator will require parameter changes with the BPW. Post #5 http://www.gearhead-efi.com/Fuel-Inj...-Injector-math

BPW is fuzzy math - what an injector is rated to flow vs. what an injector is actually flowing vs. the BPW programmed in the chip - can all be different values (welcome to tuning)
