Are you using the Bosch injectors that were with the pump? I'm no expert on conversions but I have read that it's necessary.

What was wrong with the Epic? Unstable idle, leaks or cables, or possibly all 3. Still a great pump and there is a lot of info on here including a complete rebuild.

On the Bosch automotive website, you'll find an excellent descriptive and technical document on the VE-series pumps, explaining how they work, set-up, tuning, injectors, etc.
If you can't locate it, I have a PDF of it.
