What tune are you using?

At the moment flashed to Stock to troubleshoot the car. It was a bad transfer case causing all these throttle closures. Car was hesitating bad especially at low rpms and wot. Ran a datalog after new transfer case and Zero Throttle closures and car is smooth again.
I understand these cars use the throttle plate to regulate boost but I was getting a lot of big closures (28% - 34% throttle angle). I think Ewg cars regulate boost a little better than PWG with less closures, if any...
Right now im trying to troubleshoot a rough idle/misfire with ista+. Rough running cylinder test shows misfires across multiple cylinders soon as I start the car. And Pre Catalytic converter O2 sensor reads 1.4V and barely moves at all at idle. I think it should be at .45V average. I'm not sure what else I can test to narrow down the rough idle issue. No CEL either.
