Need boost help

[allpro666]

Hi everyone! I'm new to the site and this is my first post. I just bought a 2010 ss turbo. I'm having intermittent boost problems. Sometimes when I step on the gas it has no boost, the gauge barely moves and it seems if I let off and then hit it again it works perfect! Any suggestions?

Any codes?

Ya one finally came on p2261. I think it was saying something about the turbo bypass valve?
