Car hesitates when going into boost

Hey guys, Iím new at this forum thing, but I have a serious problem that I canít figure out. So I have a 2013 GC 2.0t, I have an Injen cold air intake, ISR catback exhaust and aftermarket Hps radiator and heater hoses installed. That is all the Mods I have installed on it and my oil is only 300 miles used, as well as the radiator coolant. Plus I have a new Autocraft Gold battery. The car was driving great literally 5 days ago, but out of the blue when accelerating from around 30 and up mph, while going into boost, as my boost gauge indicates, the car starts to stutter and hesitate to the point where the car sort of gets stuck in that stutter unless I depress the gas pedal to go out of boost to stop the stuttering. I find it mind blowing that LITERALLY 5 days ago when driving, when I started to hear the cold air intake, while going into boost my car just took off beautifully, as any turbo charged GC should. So my question to you fellow GC owners is, why is this happening, any ideas as to what may be going on? Only answers I can think of is
1) NEED A TUNE (has never been tunned)
2) Replace spark plugs (maybe the ones I have on probably donít produce enough spark to support my mods?)
Thanks in advance, any answers would be appreciated.

Did you disconnect the battery to reset the learned fuel trims?

get a good BOV, your still on the stock one right? thats probably it. also check your wastegate actuator arm. you can try to replace your spark plugs. and the tune would most likely not be the issue

Yes itís still stock. And what should I be checking for on the wastegate actuator arm exactly?

scan engine codes bro. might not have check engine light but still can have a code that will throw a check engine light on later on. sounds like a misfire to me. if you didn't do anything most likely a spark plug went out.
