I mean I was expecting more low end torque but I couldn't feel the difference.Around the neighborhood plenum temp was mid 80s I think. I didn't feel anything strange so decided to go to usual mini-twisty followed by seaside straight route, 30 miles of total riding.Up climbing the twisty I turned off the heater expecting the temp to drop. To my surprise it was hovering around 70F.I started liking the smooth engine response especially from 3K to 5K rpm.Into the seaside straight I rev'ed it to 7K rpm then saw immediate drop in the temp down to low 60s so I turned on the heater again.Going around 3K rpm, the temp slowly came up again to low 70s.Then I opened up to 7K again and another drop to low 60s. I kept it around 5K and the temp went slightly below 60F.On the way home in the city street, the temp came back to 80F again.I touched the runners with bare hand and it was fairly warm around 100F I think.So far, I am satisfied with the conversion. If I can feel the low end umf, it's even better. Could it be that I have 1.5" ID runners?Should I try choking them?Also I guess the next question will be what happens on a freeway with sustained 5K~6K running. Maybe I should add one more resister. With high rpm, I think I can afford extra 70 watt.</blockquote>
