Ok, I installed my MBC yesterday thinking it would solve my boost spiking problem (bleed valve sucks) but it was still spiking up as high as 9 psi before I let off the gas. I swapped my new one with my buddy's on his VR4 Galant (hoping I just got a bad one for some reason) and had the same problem.

Suggestions anyone? I know I have the MBC as low as it can go (unscrewed almost all the way). Anyone else have these problems at the beginning?

i had the turbonectics mbc and mine was doing the same thing was upto 11psi and just kept spiking.... i ordered a halman MBC and it works alot better...no more spikes... until i got that in the mail i just disconnected the MBC and used the actuator rod... (might not be the right words to use) and i cant for the life of me think of it right now (brain fart) on the sf kit.
it actually can set it as high as 5psi.
