Default 2013 Deluxe sputtering

Just started it up after winter and is running horrible. Spitting and sputtering, lower idle than normal. Still runs and starts fine, just misses pretty bad and sounds horrible. I suspected bad gas and ran a tank with seafoam then half a tank with techron cleaner. That didn't do the trick so i changed the plugs and wires to no avail and then the air cleaner which i think made it worse. I have a thundermax tuner and don't want to take it to the dealership as they won't service with that tuner. Any ideas on other things i can eliminate?

Thanks in advance everyone.

Check for leaks in your intake manifold.

Critters get into something, maybe chewed up some wiring?
