Boost problem need help!!

[infernalist]

ok, first, no leaks in system, checked it all out. im running 19t turbos and everything was fine, then all the sudden i peak boost at 10 psi, i switched to mbc and got same result, even ran with both wastegates open and get same result. if i close system i get wastegate only boost at 6 psi. Im at a loss, help please

Check vac lines to the gates, pull the intake pipes, and check that both turbs are freely spinning.

Did you do a pressure test to confirm no leaks, or some other way?

Check your cats, if you have any.

just update, turbos spin free, i just realized car does still have cats, would that cause the boost limit? will check that tomorrow

Had similar problem with my stock 9b's. The Tee on the manual BC was loose a fraction of a turn so ditto coopkill's suggestions.
