Message	I'm running GT3071R turbos with all 2.5" piping and intercoolers.. Right up until the throttle bodies that is. It's a definite bottleneck, and at 30+psi of boost, I can imagine it cause my turbos to have to work just that much harder. I was reading somewhere that the difference in flow between stock and RobZ TB's is over 30%. I certainly don't know much about flow dynamics or anything, but I can imagine even if that number is on the high side, it would still make a huge difference.
