Recirc valve goes from plumbed in just before the throttle body, and returns to between the AFM and turbo.
You'll want a vacuum source too for it from the inlet manifold.
Thank you. Can you please check where should I add hose in intake pipes? From recirc valve back to intake? I upload photos on imgur.
In front of turbo inlet, after maf/ right after turbo outlet / or it doesn’t matter?

Stock ECU with no recirc valve is a bad, bad combination. Hot wire MAFs cannot deal with reversion, even if you don't vent to atmosphere it will shoot back out when the throttle snaps closed all the way out the compressor inlet and MAF before getting sucked back into the engine. It double-counts the air, the engine runs way too lean and stumbles if it doesn't die outright.
