I have a 2013 dart 1.4 turbo and I've had an Injen CAI on for about a year and a half and recently my check engine light (MIL) came on. I took it to the dealer and the code they scanned was p0299 which I believe they said was creating too much boost. They said if it came on again I would have to go back to a stock air intake. Now two weeks later the light came back on, has anyone else experienced this or have any suggestions?

I'd disregard what they said about going back to the stock airbox, that's bunk. Ask yourself why it ran so long and so well with the CAI? Obviously its not the CAI causing your CEL issue. You adjust the wastegate preload at all? I set mine at 7mm once, my engine hated going that far, in fact it would pop in the exhaust and buckle a bit, went back to a 5 mm preload and all was right with it again. Also, do you run 93 octane gas? Any other mods done to the car? Have you tried pulling a plug and seeing what they look like?
