the one that went bad was a manual boost controller from HKS. i replaced it with a "dejon" MBC from roadraceengineering in socal. they only work on DSM crap but the workers have sr20s and they use it with no problems. it was 50 bucks and works just fine. in fact, it was much better then the HKS and i saved $50. try using it, or you can try using a different one, but it has to be a MBC for internal single port wastegates. and make sure its all hooked up right. any questions email me at [email protected]

its well built and easy to install as well as setting the boost. its ball and spring, looks and feels real reliable, boost builds great, doesnt spike, or fluctuate. im a happy camper.

I dynoed at 260WHP 260TQ on 14psi, stock turbo stock manifold, stock injectors, just afc....and i hit full torque at 3600rpm as well as full boost at a little under that, and thats running 11afr and 20btdc timing., still rich and safe. i say screw the electronic boost controllers....not worth the $ in my opinion.
