Sure there is a big difference between stgI vs stgII.
I am sure there is a big difference between stgI vs stgII in real feel too. But I really don't know how much more realistically the feel of stgIII is compared to stgII. The gains are kind of puny. Unless the spread is dramatic and a lot higher before peak, I don't know. I have been wondering forever and would also like to see real dynos so we can see what it looks like.
335iBaller has stgIII but I don't think he had current stgII so maybe he can't really tell us. Anyway his butt dyno comparison input would be appreciated too.
