guys i got an update from gararge R with whats going on. they have told me that its not a problem with the Vafc tuning to the ECU its an actuall problem with the ECU itself. its not auto programing itself like it usually would. when there putting it on the dyno even at 3000RPM it starts to lean out and the turbo hasnt even spooled up yet, they said even at 3000RPM in 3rd gear at 80k's its dangerously lean. so when they go to tune the Vafc to the ECU, the ECU isnt doing what it should be doing so the vafc is making it go wako.
could it be a Sensor?
