p0103 code every once in awhile

So you have different tuning. What do you think is causing the problem? What should your course of action be?
Hint: Call Tony.

I have had this code pop up multiple times with Robs tuning.
I asked him about it and we never really figured it out. It happens occasionally when I drive on my max effort tune and really floor it

P0103 is airflow higher than expected. I would ditch the k&n and get an s&b or afe if it was mine. To many tests done showing the k&n is crap for me. Did you tell tony you had a round filter because you have a k&n? For an lly theres 2 different folter options in the tune files. Flat for stock filter, or round if you have an lbz intake on it. I've seen people put in the round aftermarket filters thinking its the same, and get the wrong tune file because of miscommunication. I know Tony will get it ironed out once he hears about it. It's probably something simple like above. If you put the lbz airbox tune in with an lly intake, it will throw the p0103.
I have the same code it never stays away longer than a drive cycle I've tried everything. I'm just going to assume at this point it's my tune and eventually switch.
Can you pull up the freeze framedata for the code and post it so we at least know when its happening, and what its seeing when.
Here is what Rob said to me when I was asking about the code. After this conversation, we never really discussed it anymore since he didnt email me back after I asked if it would effect performance.
"Colin, that is a voltage circuit code and if it only does it on one tune and not all, then we need to look at the reason. The base tune covers codes for all the tunes so if only the big tune is doing it then I’d look to a broken motor mount or something like that pulling on a harness. Open the hood and brake boost the truck while watching the engine and see if it moves. If it does, you most likely found the reason.

I did what he advised and didnt notice anything that indicated a broken motor mount

Nothing.
The code doesnt pop up but every once in a while.
I have no clue if its actually being caused by tension on the harness

Mine is back again, I thought I fixed it with a new maf and still nothing. It does it in more than just tune 5 also. Wondering of its a tuning problem? Could that be possible. I did just have my tunes corrected for a maf scaling issue bit the p0103 was always there before and after the fix
