Exactly where I was going. We can't tell you much without the code.
The number of O2 sensors isn't dependent on the motor, it's dependent on the ECU. If your ECU is only looking for one, then you only need one.
I personally think it's stupid that you're even driving the car, let alone 'getting on it' to pass people, with a turbo on the car trying to run it like it's N/A. I'd baby the crap out of it until you get it to the tuner. I hope you took the entire diaphram and everything out of the wastegate and not just the spring because you've likely ruined the diaphram if you didn't.
