Question exhaust backfire

i fixed my turbo today and wen i went to test drive it the turbo spooled up okay but then started fluttering when it spooled and as soon as i reached 25 psi it backfired bad, i thought i broke something but luckily i hadnt. i had my car tuned at cft and after that all ive done is swap my turbo out i have an fp white that went bad, i sent it off, it came back and i put it on the only thing i changed was the oil line i was so excited to get back on the road and smoke some v8s but this happened so i need all the help i can get

Oh yea I got a check engine light but haven't tried to test it yet but in my original post I wrote that my car was already tuned by central florida turbo and all I've done since the tune was swap the turbo but the turbos were the same it just got rebuilt I kept the same boost level the only new thing on there is a new oil line I put for the turbo
