This was my first time driving the car in a few weeks. I drove the car spirited for roughly 2 hours which caused one cylinder 6 misfire to occur which I couldn’t produce again, so I went to make my log attempts. The car did this pull very well, however I noticed odd AFR, and rail pressure dropping as well. On cold start the car now will pull 2c7b, for an o2 sensor. I don’t want to ruin the car, so before doing any logs I figured it best to send this one pull to you. Perhaps it’s a tuning issue, but if it’s a mechanical issue I surely don’t want to push the car.
