I have a 2015 f150 with 54,000 miles and My check engine light just came on today, I plugged my sct x4 and these 2 codes came up.
The P2004 diagnostic trouble codeindicates that the intake manifold runner control (IMRC) is stuck in the open position on Bank 1
The P2005 code means that the intake manifold runner is stuck open on bank 2
I just tuned my truck about a month ago, no other modifications other than a drop in k&n filter. I’d appreciate any help you guys could give me on how to fix this myself! Thank you in advance!

 

from your description I'm figuring you loaded a "tune" with the SCT device. Have you tried restoring it to stock configuration?

 

I haven’t restored to stock yet but did email the provider of the tune to see if they’ve had any complaints similar to mine. I did clear the codes and will see if the light comes back on.
