Boost Failue

[Turbo Zo1]

I just got my new combination together adn the car is awsome. When I first started out driving the car it made plenty of power and boosted to around 25 - 27 lbs. of boost. I run that much boost because that was the sweet spot for my turbo which is a PT61. Just the other day when I drove the car again it won't boost over 15 lbs. When it reaches 15lbs the car acts like it is running out of gas and surges but anything under 15lbs the car pulls extremly strong. Any help would be very appreciated.

What type of boost control are you using?

I have a HD acuator that I bought from precision.

C-16 fuel? If not, what?

Sorry, I didn't make myself clear enough. Are you using the factory solenoid, or a "Greddy", or? I'm thinking you boost control solenoid may have failed in some manner. Brian

I am using a factory style controler.
