I did multiple boost leak tests that way and I mentioned very early on that I noticed the bov leaking.its recirculated. My Wideband Goes full rich under boost then goes into 24 vacuum when I coast
Okay I think I found the problem, I tightened up the BOV Adjustment screw a couple of a turns and Im getting some boost now, but the car almost stalls when I let off the gas ( 200-300) rpmSo Its either a vacuum leak or a bad BOV ?My fuel system is not stock02 sensors are new oem Sensors
I have had the turbo completely off and the 02 housing and tested the flapper using an air compressor outside of the car
i know the turbo and the flapper are working.
Take Off your egr and see if it stuck, And see if you IAC has carbon build up.
Could also be a thermostat keeping the car in rich start.Check The Ecu voltage and the Tps Voltage for sure
