Similar experience on my 2017 with the SF intake. Picked it up 2nd hand so I'm SOL in getting much support from Cobb. I ended up pulling it off after about 200 miles and reflashing to my MAP tune and everything is back on track.

Edit: Found out shortly after swapping it out that the numbers I was seeing for AF Learning were normal - I should have been monitoring my AFR numbers instead.
