I haven't been since noticing the issue. The car idles and drives fine but above 9 psi, the AFRs spike to >20. I know this from data logging. The car was dyno tuned a few weeks ago and made 320whp. I dont know what happened since then. I don't think the tuner would have tuned without monitoring the AFRs up top, that is basic tuning 101.
I'm just trying to figure out why the turbo was not building boost uncontrollably with the wastegate disconnected. I don't think the turbo is damaged, as is responds very well, has no play and spins freely.
