Sounds like it might be something serious. My guess is, if your EBC went out you probably spiked in boost and hit fuel cut. If you did that the car might very well have gone into limp home mode. Not sure entirely about the limp home mode but I'm pretty sure you hit fuel cut. Take it into a o'reilly's or autozone and they can read your code for free. Might be something as simple as just unplugging the battery for a few minutes to reset the ECU.....or not..
