I did my own swap using an Astro van unit. See my site.
The only trouble is purging it of air bubbles. Plenty of boost that comes in progressively. The harder you push the more boost.
The mustang unit is the smallest hydroboost they make.
I love your web page and how savy you are.......You don't meet to many people like you anymore.
Keep up the good work.
