I bought a Comp 6265 and expected it to be lightyears ahead of my CXRacing dual bb turbo and to no one's surprise, it was considerably laggier. But the specs were completely different though, 6060 .58 ar to 6265 .81 ar. On the exact same tune, full boost went from 3500 rpm to about 6000 I believe and I was in a panic. After a few revisions and tricks I got it down to 4400 or so, which i considered good enough, but definitely not as instantly torquey as the smaller one. I really liked the smaller one, but it sucked on the highway.
