Awesome numbers, but I have couple of questions. How was boost measured and how come there is a variance in boost between runs? I guess the answer to the first may answer the second. I though the VF kit produced 6 - 6.5 psi at sea level and since the boost is mechanically tied to engine speed, I don't see where the delta comes from.

Thanks...
