Does the Vortech kit come with an FMU?

The problem is most likely with the tuning or the FMU. Make sure your fmu options are correct, if they are then make sure you dont have a loose wire bewteen your fmu and ecu.

There is a very simple, two-step solution to your problem;
1. Remove the FMU and toss it away as far as you possibly can, and forget you ever made that mistake... FMU's were a late 90's solution to a problem wich nowadays is being solved in a much better way, see step two;

2. Get the right sized injectors (in your case I think 440cc should do the trick, or just to be on the safe side; use either 525 or 550cc injectors) and have the engine tuned by an expert using programs like Neptune, or eCtune, or Crome Pro, or Hondata, or whatever.
I run Neptune, and I love it :)
Use a stock fuel pressure regulator with it.

You'll notice better gas mileage, a smoother/stronger running motor (you'll actually gain hp by doing what I advise you), a more reliable or durable engine, etc.
