boost issue HELP

[87gn1]

Last night I went to go wot and my boost went up to 25 psi. Myo2 reading are all over the place. My set up is stock chip turbo stock what would make this happen. Knock went up to22+ and I let out of it as soon as I seen it rise. I do not have a power logger. The knock readings came from my scan master. When I drive nice under about 15 psi of boost no knock runs good. Any advice is appreciated thanks in advance

at 25 psi you better be running 110 octane. TT chip would help
