Default Is this the right valve ? Photo ....

Is this the right type of valve to control the amount of pressure bleed from the waste gate solenoid line ?



I have a Shiv Ecutek dyno tune ... but have recently added a ScoobySport downpipe. I'm getting major boost spiking ... and have heard that I could remove the bleed hole (that I believe Shiv added) in order to control the spiking. Removing the bleed hole (I actually taped over it) however brought my boost too far down.

So I was told that I should add a controllable valve, off of a T connector ... in place of the bleed hole section ... to finely control the pressure bleed.

I know I need a retune ... I just can't get it done in time before this weekends AutoCross ...

You could just use a MBC for the time being. Obviously, get retuned as soon as you can. You could also do some user tuning if you have DD.

You can use a small brass needle valve from a hardware store as an MBC. The one pictured will probably not work. But make sure to get re-tuned asap and go easy on the boost in the meanwhile.
