Then drive the car for a while longer and see if the trims settle, depending on your driving it takes around 100 miles. IAM=Ignition advance multiplier, it is just advance multiplier on the OFT menu.
One of the threads I found searching “BRZ Mishimoto CAI scaling” was a thread from him talking about it needing some tweaking so
Even the OFT base maps took some maf scaling on my car with a stock intake. If you are going to spend all that money on mods why not take the time to log it and make sure everything is good. Reading your first post it did not seem like your fuel trims were good and it “sudden needing rescaling.” I thought you said it was -5% after installing new parts and then you reflashed and it went off further.
It seems like you are looking for an answer you want to hear and not actual help.
