R32 Gtr Low Idle Issue,stalling When Cold Burning Rich!

[Goved5]

We recently installed single turbo setup with twin mafs and external wastegate on RB26, the car now does not idle when cold, does improve when engine warms up, It doesnot have a problem during acceleration though. The aac valve when adjusted does affect the idle hence it does work.Not sure if there is a vac leak somewhere.Any ideas what could be the problem?

What ECU?

is your cam cover plumbed back into the intake? i.e. post AFMs?

Nistune, but currently the ecu is stock, the cam cover breather pipes are open to atmosphere, I tried blocking the breather but no difference, it is still idling poorly. So to answer your question, the cam cover pipe is not connected to post Afm's.
