There is a benefit to dual inject, the valves should be cleaner.
For me looking at it, I think I was just fixated on E85 because I already have done the conversion. I'm completely happy with my current setup and may never go to a pulley bigger than 4.5 on my D1X (7 PSI). The car is traction limited to about 80 MPH of so. It would be interesting to put the LT4 stuff on and inch up to see how much more HP the car will do with E60 or E85 on 7 PSI. I don't know, Ted any ideas?
All the money I save I can sell my ported MSD and go to a Goetz intake, just becuase it is such eye candy...

The cleaner valves can also be achieved with simple water injection and is the only real benefit of adding port injection vs direct injection.
I would recommend the fuel system upgrades and see where it takes you.
It is almost comical reading some of the comments of how people feel the fuel system is the least important when in fact it is the most important part of any build.
It takes fuel to make power first and foremost before any other mods.
Spend your money on the fuel system I know it is not as glamorous as purchasing a supercharger or NOS system etc but it is the foundation on which all power package should be built.
