How do we do FFF'S (fiat forum friends)?
I just wondered if there Is a certain bleed valve I have to put on my gt3? I put an incar one under bonnet that shouldn't make a difference should it? Thanks once.

By bleed valve I'm guessing you mean a boost bleed valve, or dawes device as they are commonly known. No you can use an in-car one or an engine bay one. They are the same thing really - just the in engine bay ones just bleed out the side of the body of the valve and the in-car ones have a fitting to run and pipe back the bay so its not bleeding the excess boost into the cockpit.
Turbosmart ones are very good quality

I've got a 3way bleed valve, do I need to disconnect the wires from the pierburg valve? I left mine connected and adjusted boost and boost stayed the same? 3way connected to turbo and actuator.

no, leave the pierburg connected electronically or the ecu will put the EML on cause its not there.

check you got the valve the right way round - they should be a particular way round. Might just be crap quality and not work - have had this happen more than once.

Cool Thx will try a different one.
