I had this exact problem with my car a few years ago. It took me a year to figure it out. It was my AEM fuel pressure regulator. If you can install a stock one back in try that. A rebuild kit is only about $30 if that is what it is. I originally thought that is what my problem was but according to the fuel pressure gauge it was working. I finally decided to swap it for the stock one and the car ran like a dream again. A whole race season down the drain for $30.
