How are your EGT's reading?

I had that problem before when I turned the boost up on my car. I was leaning the hell out of my engine. Seems like you have a number of mods to increase airflow. I don't know how 2G's go about this, but you might be leaning your engine out. A fuel pump might be the next thing you wanna buy. And maybe an AFPR for good measure. Fixed my lean condition right away.
