Run it in parallel to cap boost else you will loose part throttle drivability

but my mbc is two parts not like the one in the picture?!

Not sure what you said there...

I am not familiar with that type of bleed valve but from the picture I would assume you use the part with the screw bit on top and hook it up as per the picture above...

I doubt its a particularly accurate one so may take a bit of tweaking to get right (Forge UNOs is the one I would normally use) but you will need a couple of T pieces too... the supplied 'diverter T' might work as one of them but again, not something I have used so couldn't say if that part is any good..

looks like a bleed valve, not an MBC.

That would work better than the first one but they are still pretty rubbish tbh... these types of bleed valve tend to be too coarse on adjustment...
