This is why BOVs are stupid.

Yes, but TIAL dont offer any stronger spring Sad

But still strange why was all good before about month and at once is crazy ...

BOV will stay opened and MAF counting with this air so much rich Sad

I dont know how to set that i want bov closed as soon as possible.
No dtc coded out. Maybe much vacuum - i have 10psi spring in bov and in manifold is about -0,7-1b ...

hmm ok I forgot about the BOV part , I never never never recommend them , glad you sorted it out anyway Cheesy

Not so easy - at idle is about -0.6b, in deceleration or from higher revs is -1b and this is problem - bov is opened and when i put pedal engine run rich due MAF reading vented air.

Will be solution stronger spring or closed bov? Dont know why is too much vacuum at once. Other aspect is when will bov open when will be spring for -1b and is -1b in deceleration ...

Or will be solution opening throttle plate for lowering vacuum?

The solution is to let the ECU control a recirculating bypass valve.

finally your o2 sensor control active cames "1" or not?Did it had any activity?I have similar problem.i upgrade 180Q(ajq with 8n0906018b ecu) with 225 parts(flash my ecu with 8n09906018f stock file)but i don't put secondary air pump.My MAF reading right,but on my lambda sensor status only sensor heater and sensor ready values change,the control active value stays always "0".Any solution?
