i putt my new ssautochrome wastegate on my custom turbo manifold that sits in my 90 prelude si. i hooked it up with my new airesearch turbocharger and a new manual boost controller. i take it for a spin and it went well over 10psi so i turned it down. then today it start to make a whisling noise. like it was leaking somewhere to prevent it from boosting. then some times it would boost but thats it. goes right back to the slow whisss noise. what could it be. i checked my conections and i also took the boost controller off. i have a 6 psi spring and i was rolling around on 10psi cause that was the lowest i could set it at. it ran fine until mid day today.

help please
