Ok - Update for everyone. I ran the entire tank of old gas and the new 97. I then went to the same Holiday gas station I usually do, got my non-oxy 91 and filled up. I then logged and saw that the IAM was at 85 from all my recent driving, so I reflashed, and went and drove around for about 20 minutes. I checked the logs when i got back - sure enough IAM dove to a 90 during that time.
I can't seem to find any other symptoms as to what may be going on. My Tuner (motoeast) said they would do a smoke test to see if there's a boost leak, but I feel like I would see the loss of boost in the logging.
I'm running low on options - so i'm just brainstorming - Should I remove and inspect the plugs and see if there's any evidence there? I've also thought about trying to do a compression test, but i'm not sure how I would get the tester in the spark socket with the motor still in.
Any other ideas?
I've attached the 2nd of two logs from my now 91 oct tank of gas 20 mins post flashing. The IAM did start at 1 after flashing of course.
Thanks!
