is it possible to change my dual stage to the single stage ? some photos are attached. can i just get a brass plug for the end and cap it ? and just use it like a single stage turbo xs boost controller ?

Sell that thing to somebody who can use it and build yourself one... or just get one of these.

For the low boost you're talking about, the cheap eBay one will work great.
Brain shows how to build one in the DIY projects section. Here's an almost identical approach: http://www.geocities.com/chmwatson/FAQs/mbc.html

I've always wondered how those dual stages worked.
it looks like if you plug the port for the solenoid then you'd have youself a normal MBC. If it boosts too much at the sofest spring setting, you may need to cut a coil or two off.

there fun as hell! had one set at 8 psi and the other at 14.5. you can flip the switch while already being in full boost. its a blast

Yeah I understand the concept, just would like to understand what's acutally going on the change to boost levels. Like when the solenoid is activated how exactly does it override the first spring setting.
