Ok, should I be concerned? Best gas around here is 92 Octane. Car is stock (except now has a higher flow air filter). Didn't get a baseline with stock Rom before logging. Started with the 93 OFT and my IAM was roughly around .8 most of the time (usually lower) earlier post has the 93 log. Swapped gas stations/brands and went over to the 91 flash. Now the IAM was bouncing around .45-.70 usually. Only once did I see it briefly hit 1.

So this was concerning me, so I decided to go back to the stock Rom. Granted I only have about 50 miles on this so it hasn't "learned" completely so I'm not holding high hopes. I'm seeing it bounce between .25 (briefly) to about .65

Any idea what's going on here?
