08 cobalt ss turbo problems!

Hey guys im new here. I have a 2008 turbo cobalt ss. gm upgrade tune, injen cold air intake, injen charge piping. i had the turbo replaced in december due to a failed wast gate. i recently put back on my cold air intake and charge piping. i am having trouble with boost spike and boost lose. i called injen to see if it could be the intake causing the problem since the intake is tuned to gm standerd specs of the vehicle and they said that it very well could be due to the air to fule ratio being throwen off. i was told to go dyno tune it. just wondering if anybody has had this problem with injen intakes? should i keep it on and go dyno it? or replace the intake. any help would be great
