Ok I picked up the Turbo xs dual stage boost controller from a guy today. I asked him if it worked and everything was there that I needed and he said yes and it's the way he ran it on his car. So I get it and get home and start really looking at it and I notice the top is missing where you adjust the boost controller. Here is a pic it's supposed to have 2 tops to it.
Here is what it's supposed to look like:
Then I tried to spin the top that is still on there and doesn't move. I got some vice grips and tried to spin it but it's stuck and wont budge! Am I trying to adjust it wrong or is it really stuck and how should I try to break it free without breaking it? Also is there a way to adjust the top one somehow even though the top is off of it?
Here is a couple more pics. O and yes I do have the thing that plugs in and goes to a switch. Also I will be getting a fitting to plug up the extra hole.
WHAT ELSE AM I MISSING OR IS IT NOT USABLE?
