1997 Aero Running rich and misfiring...

Lately my car has been misfiring, bucking and no longer accelerating the as hard as it did. Its currently setup at Stage 5 tune, and max boost I'm seeing is 15-17. Rather than 22-24 I was getting when I installed the Ecu/injectors/turbo. Recently I installed a wideband sensor, and the car is running awfully rich. I've been trying to diagnose this issue on my own for a while, but finally gave up and took it to a friend. He plugged into the ODBII port and said that the car was running in "open loop", and that the coolant sensor was reporting between 253-259 degrees. He said he would start by replacing the coolant temp. sensor and thermostat and see if that changes anything. Anything else I should order and install that may be not working the way it should?
Thanks.
