Yep, even though I had no major issues with all the combinations of straight-tubes that I used previously, I was immediately impressed with the lower voltage noise after switching to the Tuner Tube. This is most noticable when I am lugging up a hill in 5th gear at 1100 RPM or so on the back roads around here. I hadn't previously thought this was possible with a slightly lopey cam that wants to idle at ~800 RPM. That and the fact that it can flow to over 3000 kg/hr using the 85 mm tube and it's an all-round winner for me.
