Why am I boosting at 12?, Still stock, thought max at stock was 10... Options

[Green_MachToy]

I had a stud in the Exhaust manifold break at the head. In repairing it, my car is now pushing 12 pounds. I still have the stock ecu, no boost controller (until tomorrow), no FCD (stock max is 9.7). Now to give you a few more specifics: A friend of mine put a plastic t in my lines to trick the wastegate into allowing more boost. This caused me to reach 10 (probably 9.7, but meter isn't that detailed). In doing the repair I took the t out. I also found that my Cat was bad and took it out as well (it will cost me $300 to fix later). Replaced a crush gaskit after the stock down pipe to the 3" exhaust. Got everything together at approx 0130, and took it for a test drive. Found a couple of vacuum lines had worked themselves off of the stock BOV. Fixed those, and off again. Ran at stock 7 pounds of boost. Placed the t back in, ran at 10. Next day...got in the car got on it to pass a car...14! Took the t out, down to 12! It does seem to creep. When I hit the gas, it will jump to about 8-10, then steadily walk up to 12 as the rpm's increase. Did my wastegate go bad? I was thinking the increased flow in the exhaust from having no cat may have been the problem but it ran stock the night I did everything. Any ideas?
