I have a supercharged GT and today I was datalogging my car in 3rd gear from 2000 rpm to redline. Everything seemed okay until I got to redline and let off the gas. Then I heard the bypass valve go off and the car died. Since then I have not been able to start it again and had to have it towed back to my apartment. What should I look for as the problem? It still turns over and almost seems like it's going to start but won't. If I press the gas down while starting it fires up and instantly dies.
