Default Increasing boost, need a bigger wga..

Hey guys, I'm trying to up my boost using a mbc on the stock wga, but it's struggling to keep the wg closed around 12psi (it jumps to say, 12.5-13psi, then drops town to 12 and waves up and down while trying to bump it up to 15-18), any suggestions on a wg actuator solution that will bolt-on using the fm bracket? Something that can handle 20psi and keep that door closed..

Other thing I was thinking of, was if the mbc might not be holding it closed, but I dunno... I've gotta drill+tap my IC for a hose for my wga, its running off the turbo right now (I know, I know, but I have silicone hoses)

Pull the signal from the in between the IC and the TB and try again.

Are you sure the MBC is working correctly?
Have you tried tightening the arm on the wastegate?
