I didn't read through all this, but I have dynoed 20 plus engines with EZ efi with the Performer RPM intake. Makes the same torque and HP as carb. These are hyd roller 550 to 575 hp engines. Intake works well with the given rpm range, 6000 max. Lunati hyd roller lifters float at 5900 anyway. More hp and rpm, I use EZ multiport and Torquer II with just enough injector to support the power. Smaller injectors atomize better than larger. 36 lb pico inj atomize very well. 44 lb not so good. Have to run more timing to make the same power as smaller injectors. Hope this helps.
