At the dragstrip yesterday I would shift into a gear and when I would first floor it it would hit 18 psi which was my setting but then drop to 12 psi through the gear. I'm running Aem tru boost and I'm not sure if its how I have it set or what. I am also using kind of cheap bovs from my last setup... I was just wondering if anyone had any ideas to what could have been happening. Btw I had a 1.7 60', 7.85 1/8 mile and a 12.14 1/4
