Only 7 psi

i got a 08 cobalt SS, stock other than k&n short ram intake, 130xxx, Just had my turbo give out. Replaced said turbo with new stock ko4 turbo from zzp. Replaced all oil/coolant lines. Car runs good unless you floor it. It hits 7psi and has less power compared to normal. No lights. Also when I first started it this morning it didn't seem to do the "cat warmup" like normal. It usually sounds like a howling dog when starting in the cold. Not really sure what to check. Any idea would be appreciated
