hydraboost issues ???? help

[78macho]

I recently installed a Hydraboost from Hydratech have some issues.

1. very noisy all the time (ps growl)
2. fluid foams up as soon as the car starts, it has about 4 hours on it now.
3. after releasing the brake pedal the brakes hold for a second or two

Im using a Billet Specialties Tru Trac system with a Maval pump and Billet Specialties reservoir. Paul @ Hydratech said "it should work fine"

It appears to have alot of return pressure into the reservoir, more than it had pre-hydraboost. Is this why its foaming? is one PS fluid better than another?

I've been told to drive it and it'll get better but the longer I drive it the more noise it makes.

Anyone have a fix or suggestions? please help!
