Technical Bleed valve
coupe has a bleed valve as standard, but its an electronic one controlled by the ecu. i guess you want to fit a manual bleed valve to determine if the electronic one is still working? this is an ok reason to fit a bleed valve, but i would not fit one permenently because the wastegate will open early and spooling will take longer compared to the stock electronic bleed valve.
you fit the bleed valve betwen the turbo outlet and the actuator. it may be 3 way but you can ignore the bottom bit, you just need to connect to the port on each side.

You should be able to use the dump valve without cutting anything...
Simply remove the standard plastic dump valve from the lower pipe (as your looking down into the engine) coming from the air filter and block off the hole where it came out.
Then using the same pipework, connect up your new dump valve but you'll need to fit it to the pipe nearer the top of the engine bay coming from the intercooler. Connect up the vacuum hose from the inlet which came off your standard recirc dump valve.
Hope this helps....

marco any possiblility of a pic of your bleed valve just to refresh my memory on how you showed me to fit it?
Firstly, you need to determine WHY the boost is lower than before, have you connected the pipes up correctly? you may just mask a fault.
My guess is your actuator isnt properly adjusted. Connect the pipes from the compressor housing of the turbo directly to the actuator and see what boost you are getting, this is base boost.
Secondly, a bleed valve keeps the wastegate SHUT for longer, as it 'bleeds' the air off to atmosphere. The turbo then has to make more boost pressure to OPEN the wastegate. Just be very careful using one, start with it wound all the way IN if you must use it.
Also, you said "ok so the vacum pipe goin to the actuator needs a snip and the valve going in the middle!!" that is correct, the other pipe needs to go to the compressor housing.
Overboost: He isnt talking about a dump valve, he is talking about a bleed valve, completely different things.
Turbotipo:
The bleed valve connects to the compressor housing (bottom pipe in this case) and goes to the actuator (top pipe in this case)
It doesnt matter which way round they go, just be careful with them, you can easily melt your engine!!
Get a proper boost controller, like this
Hope this was of use to you
