So, 2010 Cobalt SS/TC 6k miles on it. Mods are CAI, IC piping, downpipe and 22psi tune. I thought I had a small boost leak, so I tested and did find I lost a vacuum line off the lower IC pipe. I tested by hooking an air compressor/boost leak tester to the intake side of the turbo and ran 20psi through the system. Everything was more then fine before i started. I've done this 30+ times on evo's and sti's. Fixed the small boost leak.

I start the car, MASSIVE smoking, blueish white smoke, defiantly burning oil. Drove it a lil bit just incase the test shoved some oil through the pcv valve and was just burning off. I boost, a ****** cloud. Tried a few runs, clouds. What the hell happened? Can these cars not take a boost leak test? Or a better question, what the hell could I have done? Demodding and going to the dealership tomorrow, so I'll know soon enough but hell, this is retarded.
