Hey guys,
I promise I have searched a lot and have not found a great answer to my issue.
I previously had a Perrin CAI and the OFT Stage 1 tune that I scaled using Perrin's Scaling.

I just swapped the stock intake back on but kept the Perrin intake tube. I reflashed with the unmodified Stage 1 tune and am now getting very low IAM. Anywhere from .45-.65. I thought it may be gas, but I filled up at a QT with 93, hoping that it would help, and it hasn't.

I am wondering if any of you have any insight as to why this may be?

I also regret never having paid attention to the IAM with the intake on.

Is there anything from the intake install that could be causing my issue?

Also forgot to mention my LTFT seem fine, less than 5%.

Also this is on a 2013 FR-S with just over 100k miles.
